Wordpress: Very slow loading - ajax

I'm not a developer and our original developer doesn't know how to fix this, so I'm pretty desperate, hope you guys can help!
I have ran the website through different analysis:
Pingdom: http://tools.pingdom.com/fpt/#!/dlRIXt/www.sanefitnesshk.com
Google Developers: https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fsanefitnesshk.com%2F&tab=desktop
I've already installed W3 Total Cache.
If you need any more information, please don't hesitate to ask as I don't even know where to start to fix this problem.
Thank you so much!

Try to "defer parsing JavaScript to reduce blocking of page rendering".
Hope it helps you some extent.

It's probably admin-ajax.php that does the most damage here. I can see it loading for 16 seconds, and no HTML rendering takes place before this.
You can see it with Chrome Developer Tools, but more clearly on webpagetest.org where you also can see the screenshots from different seconds.

why would https://secure-a.vimeocdn.com/js/froogaloop2.min.js delay my site load time?

It seems just recently my site's load-time is being delayed for about 30seconds due to Vimeo's https://secure-a.vimeocdn.com/js/froogaloop2.min.js.
What i don't understand is that if i follow the link directly it loads up instantly so i am not sure why it would it cause load time delays on my site?
i already checked with my host and they see no problem on their end.
anyone have some insight?
For anyone who comes across this as well, for some reason that link just doesn't seem to work anymore, although I couldn't really find any news as to why, the newer link is this one:
https://secure-f.vimeocdn.com/js/froogaloop2.min.js
That works as of today

Mozilla Firefox resource for bug reports and suggestions

I use Firefox for about 90% of my overall browser usage experience and periodically discover bugs or strangeness in work, also from time to time I have suggestions for improvement.
So I think that it's useful for Firefox community to know about potential or actual problems. Is there such resource to create quick reports (I'm at work, for example, and haven't enough time for advanced conversations)? What is the easiest way to report bugs and suggest some new ideas? May be there is some addon for this purpose?
Thanks in advance.
Good question! Depending on the problem you are seeing, there are different strategies for efficiently reporting the issue. Efficiency in this case means the reduction of the time that passes from your report to actually get somebody to take a look at it (and then decide what's next).
Here's a set of ways you can use to get in touch with the community (disclaimer: I'm part of it):
Bugzilla: it's the one stop place for reporting bugs for Firefox. I know it's a bit cryptic at first, and there are plans to improve the bug reporting workflow. There's a comprehensive article on MDN that explains how to write a good bug report that's actually helpful. Don't get mislead by the word "bug": Bugzilla is also used to track the development workflow and discuss enhancements.
webcompat.com: if you're having problems with a particular website that doesn't get rendered properly, you could still write a bug report in Bugzilla. However, the webcompat website (still supported by Mozilla) is more suited for this kind of things. It also features a downloadable Firefox addon to speed up filing website compatibility issues.
Github: some components (Testpilot, ...) live on Github rather than in the central Mozilla repository. If you're experiencing issues with them, you could file an issue on the github page for the specific project.
irc.mozilla.org: (discontinued) this chat server allows to get in touch in real-time with the Mozilla community. There are several channels you can hang out in, even using a web-based IRC client. People are usually very willing to help. This is not the best place to report problems, but still a good place to raise awareness about your bug if it doesn't get triaged (i.e. assigned a priority and discussed) within a week or so.
chat.mozilla.org: as of May 2020, this replaced IRC and is the new recommended mechanism for synchronous communications. See the related wiki.
I know that's a lot of info, but it's easier than you think! If you feel like you don't know where to file bugs, just go to Bugzilla. Please do not hesitate to ask if you need more help and.. cheers for willing to report bugs!
Updated May 2020: Added Matrix and marked IRC as discontinued.

How to improve Firefox performance?

I usually use Firefox as my main web browser, but one of the major problems it has is its memory consumption. After an hour using it, and with no more than 20 tabs opened, it can consume more than 1 GB, and this memory isn't released even if I close the majority or the tabs I have opened. The only solution in this situation is restarting it.
I have read some articles about tuning Firefox, such as:
http://forums.mozillazine.org/viewtopic.php?t=53650
http://sswam.com/2011/05/19/tuning-firefox-for-speed-enable-http-pipelining-etc/
http://www.technical-assistance.co.uk/kb/ffconfig.php
But the solutions given in these articles didn't work for me.
Has anyone managed to tun it to not consume an excesive amount of memory?
Thank you in advance
I had the same issues. After some digging, I've found this out:
https://support.mozilla.org/en-US/kb/firefox-slow-how-make-it-faster
It was very usefull to me. Hope it could help you too.
EDIT: The original link I've posted is offline. I dig again and decided to refer to this Mozilla's tutorial because it covers most of the hints I used to improve FF.
How many extensions/addons are you running? A large part of your problem could be that. Also, if that does indeed turn out to be your issue, a lot of the memory those addons take is tab-independent. So you're right to assume that the only way to stop that is to restart it fully. I use Chrome, so I'm not super familiar with whether or not you can disable extensions/addons individually without shutting your browser down, but I'd look into the possibility of that.

Website running slow in IE with no specific reason why

We have a website that a few people are complaining about it running extremely slow. We're struggling to figure out why and to even recreate it. Most are mentioning that it's running slow in IE.
It's not limited to any specific section of the site, just the whole thing in general.
There's been several developers creating/adjusting the code so it's overly bloated but we can't see any specific reason why this should happen.
Can anyone see why?
We've also run a speed test:
I was running a profiling test with IE on your website and there is a call to:
http://www.playforce.co.uk/-ms-transform.htc
Which is giving error 404 not found and taking 1 second to complete (0.91 sec).
If is found all around your css under this line:
behavior:url(-ms-transform.htc);
Am no expert !! Am welcome to better suggestion and corrections of what i am about to say
You can try using a trial version of Borland Silk meter ..
They tend to measure the speed with which each element loads using various browsers and various geographical locations which are configurable by you.
Also , since only some of the user's are complaining about the speed being an issue you should also check the speed of their internet and their browser version and other addon etc of those users. Because sometimes the problem is not only with the server .
Try the above tool to confirm nothing is wrong in your server and then proceed to checking the client's browser and network.

Do you use online or local help in Visual Studio / Are there downsides of one over the other?

Well I am sure that most people have seen the following:
This time, I did not install the local MSDN so I do not have the option of Local help, however I usually always use the first option of look online anyway.
I was wondering if there are any downsides to not installing MSDN?
The only one I have found so far is that dynamic help does not seem to work. As this is a feature I love, I think I will install MSDN.
I was just wondering, are there any other downsides and what do others use?
Edit -
It is hard to really select one answer here and I did various experiments and came up with my own conclusion. They are all good points so +1 to everyone - I was going to put this as an answer and mark it, but that feels rather cheap... so I have edited the question and will have to think about who to mark as answer.
I have been experimenting with different combinations and it is weird to say the least. On a new project, I just pressed F1 at random places and it is amazing that the differences are huge in the pages which are returned - For example, just selecting a <form> tag and pressing F1 came up with 100% different results between online and offline help.
I love the dynamic help feature but I always have an internet connection... I am confused and just not sure what I should do! Another benefit I have found is that through offline help, you can sync the sidebar and navigate around VERY quickly and find other articles - which is much harder online.
I think I will install help, but I am really not that happy... I hope the help feature is improved in VS2010 (haven't had a chance to play around or see) because it shouldn't be this hard to try and choose!
#blaketaylor.nameindex.ht - I personally find Google a bit mucky when I just want to figure out one property or item etc... I like looking in MSDN / Documentation first as there is usually a good example and then just look at Google after if I cannot figure it out - the dynamic help feature is a brilliant feature which I love and skips straight to the correct part in the library, and you do not get this without installing help.
#Shiraz Bhaiji - Agreed with your points, however, I think 2GB's is not really huge. I like your comparison.
#Yassir - It disabled the dynamic help feature, 2GB's isn't huge, I do like Google and SO but I like to try and get it done on my own first.
#Stephen Nutt - Agreed about speed, but it isn't really by much. How do you see local and online help at the same time? I love Dynamic help but when I click a link, it goes straight to local help and I see no options.
I have never found the local help to be of any use. I stopped installing it years ago and have never looked back.
Google is my help.
The main downside to not installing local help is that you do not have access to help if you do not have access to the internet.
The benefits of not having it local are:
Always up to date
Does not use space on your harddisk
I really don't think you might need it unless you don't have no internet connection all the time
also it takes about 2Gb of your hard drive !!
All you need is google and SO :)
I always use local help - it is much faster to navigate around in. When I do a search it always brings up the results count in my local help and online, if I see nothing in my local help I just click on the online tab and see the online search results.
