CPU consumption
Hello !
I've just installed ATS on a Debian 6.0 (but with squeeze repository in
order to install ATS using packages) on Xen server host (other VM on the
same host work like a charm).
ATS is now setup and works as a reverse proxy but it consumes CPU even
with no connection (that's a lot for doing... nothing !) :
For example the result of the top command :
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1929 traffics 20 0 93192 31m 1964 S 11.9 53.7 0:02.45 [ET_NET 0]
(don't take care of the memory the machine only have 64MB of memory, for
testing only).
I've tried the same setup on a Virtual Box VM and the result is the same.
Any idea ?
Thanks !
Matthieu

We have a bug for that: https://issues.apache.org/jira/browse/TS-1365

Most likely the event loop timeout is too short for the VM. The shortest
timeout should be at least 10 msec in most cases to avoid busy waiting.
Practically speaking, we should be able to use a 1 second timeout and just
interrupt the thread via the eventfd mechanism.
Can we get a specific repo list: Virtual Box Version + OS type and version
+ ATS version and build flags (if any).
Thanx,
john

I've tested on a server with a Quad-Core AMD Opteron(tm) Processor 2376
HE (with on core setup for the VM with ATS) and I've tested on my own
laptop with an Intel Core 2 Duo P7450.

ACK, ACK, ACK.
I was just surprised it started!
I have noticed this behaviour a long time agoe on FreeBSD, I
didn't know it's spread over to Linux in such a way already.
How many cpus/cores/threads does your server have?
@devs: Has anyone observed this kind of behaviour on a system
where there is a usable DTrace?

OK that's good if the CPU doesn't explode while in production.
But I think that there is a problem because something that do nothing
should not use CPU. Otherwise what ATS does with that CPU ?

well, it's not that much, around 100 MHz in
VMware vCenter and the really important thing
is that with some hundret simultaneous requests
the CPU load stays moderate compared with the
origin server

Hello,
Sure it's very little :)
But I've the same problem with another VM with 512MB of RAM. Even with
64MB of RAM, ATS starts and works fine (with caching enable). So it
isn't the problem.
Thanks
