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.

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).
64 MiB seems like really little.
Did you disable caching? Otherwise I cannot imagine ATS even
starting
properly with that little RAM
but this has nothing to do with the CPU usage
i have here a dedicated trafficserver-vm in production
with 4 GB RAM and 10 GB RAW-cache-disk which also consumes
all day long some percent CPU usage while any other server
is completly idle from view of CPU load at night
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?
