An application I cannot change is dropping some incoming UDP packets. I suspect that the receive buffer is overflowing. Is there a registry setting to make the default buffer larger than 8KB?
From this
To set the default size of the Windows use the following DWORD registry keys :
[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet\Services\Afd\Parameters]
DefaultReceiveWindow = 10240
DefaultSendWindow = 10240

Here is what I see in MacOS Activity Monitor, note %CPU column.
First item (Xcode process) shows 122.4 value. Any idea what it represents? If it is 122.4% then percent of what exactly?
The %Cpu usually represents the % usage of a single core on your processor. If you have a quad-core, you have a total usage possibility of 400%.
Your first process in your list has 28 threads spread accross more than one core which are using more execution than a full single core.

I'm trying to use ALT + 0176 to get degree sign (°).
But when I use ALT + Num 7/Home, I am redirected to the browser homepage.
Sounds like you are using a laptop that has a numpad.
The alt characters I believe need to be executed on a numpad and not the normal querty number row therefor you need to enable number lock. In order to access those number keys, you need to ensure Num Lk is toggled on.
The Num Lk key should remove the default binding for Home and replace it with Num7

why conky duplicates the display after every minute as the picture
This looks like a common issue with Conky and graphics. You can try enabling double buffering:
# Use double buffering (reduces flicker, may not work for everyone)
double_buffer yes
or fiddling around with the own_window, own_window_type, and own_window_transparent settings.
I solved the problem by own_window_type normal
in the file ~/.conky

my computer has ubuntu 14 installed. There are a total of 40 CPUs, and 260G memory.
I use top command line to check the status of the processes. I was expecting that for each individual process, the virt value should be approximately equal to 260 * mem%. However, it is not.
Could you anyone help me to figure out why?
Thanks for any input:))
The MEM% column shows the amount of physical memory that is being used by a process. This amount is called the "Resident Set Size" (RSS) and is given in the RES column. The amount of virtual memory on a system is effectively unlimited due to the fact that each process has their own LDT (on x86; other architectures' MMUs have their own equivalents).

I am trying to get bandwidth value of Wan interface in Open-Wrt router (WRT54GL) using
OID: 1.3.6.1.2.1.2.2.1.10.4
But I keep getting value around 4174517174
I was doing some calculations and it does not make any sense:
4174517174 / 8 / 1024 /1024 = 497 MB/s
Does this value contains more info like time or something or my OID is incorrect ?
I have got the answer. Its the whole traffic which has passed trow this interface. To get the bandwidth you need to get the difference between two past values...
