Okay, this is creeping me out - I see about 1500-2500 of these:

TIME_WAIT may have got lost....
It's probably harmless.
The TIME_WAIT state is what a socket goes into when "lsof -i" to see who has those sockets open and see what's doing it.
Connections (1500-2500 of them every 2-4 minutes).

The proc(5) manpage describes iowait as "time waiting for IO to complete". This was mostly explained in an earlier question. My question is: while waiting in blocking IO, does this include waiting on blocking network IO, or only local IO?

It means waiting probably counts time....
However, it will include time spent waiting for network file systems like NFS.
As far.
The iowait time is the amount of time a process spends in the kernel I/O scheduler.

I was reading about using the SO_LINGER socket option to intentionally 'assassinate' the time-wait state by setting the linger time to zero. The author of the book then goes on to say we should never do this and in general that we should never interfere...

In TIME_WAIT you are just waiting for any stray packets to arrive at the local address.
It occurs after a TCP FIN on the local side followed by a TCP FIN ACK from the remote location .
TIME_WAIT is absolutely normal.

Is there a vmstat type command that works per-process that allows you to see how much time a process is blocked waiting for I/O , time in kernel and user code?

Strace will show you how much time is spent in system call, however it won't tell you how much of this time is spent in waiting....
For, block layer information, wait/blocking/busy etc..., very in depth, there are quite a few.

This is my first time posting here (besides my intro), and I'm having a similar problem with two friends: constant lateness.
The first has 3 children, a home business and a very busy life. Over the last year, she's gone from occasionally late to always...

How do you tell a Ruby program to wait an arbitrary amount of time before moving on to the next line of code?
thanks
Answer Snippets (Read the full thread at stackoverflow):
(This is useful when you want a thread to sleep until it's woken.)
It's pretty easy:
sleep(num_secs... .
If you just run sleep , the process will sleep forever .
Be careful to give an argument.
Sleep
Use sleep like so:
sleep 2
That'll sleep for 2 seconds .

Question about the MAC-protocol of 802.11 Wifi.
We have learned that when a station has received the data it waits for SIFS time. Then it sends the packet. When searching online the reason that is always mentioned is to give ACK packets a higher priority...

Rather than the server sending back 400 ACKs, it can simply wait until the client-before time....
As long as the wait-before-sending-ack time on the receiver is less than the retransmit-if-no-ack to the server.
Such a strategy.

Is there a linux command that allows you to see a processes IO wait time vs. CPU time? I'm trying to see whether some processes are IO-bound or CPU-bound.

I am not sure how you see the I/O stats for a particular process .
Simply using top should give let you know if the a particular process is CPU or memory bound .
If you install the atsar package you can look at the system's CPU and I/O stats .
