Aida CPU usage

Hi all,

we are running two Aida based server implementations and have observed
that they seem to constantly use a significant portion of CPU (20-35%).
Has anybody seen something similar?

Another question somewhat related:
has anybody done an Apache compatible access logging for Aida/Swazoo?
Would help us to track and analyze the access statistics (we use awstats
for that btw).

Michael,

I have a VW and a Squeak image on the same server, each running a couple of Aida sites and have not seen anything like that usage - mine are normally less than 5%.

Hi Michael,

I have 10 Aida images running on my server, and each one uses less than
1% of the CPU on a 2GHz processor. Sometimes it grows temporarily to 6
or 7%.

Which VM, image, Swazoo and Aida version do you use?

Cheers!

Nico

Squeak and pretty much the latest Swazoo/Aida versions.
But just realized we are still using an ancient Squeak Linux VM (3.6)...

Yep, me and Ken Causey just solved similar problem on Aida/Scribo
running the Squeak website. This image eat 30-40% of CPU constantly,
without any obvious reason. After we closed all windows except
Transcript and one Workspace, CPU drops down to few %. Funny, yes, but
true. Can you try the same too?

There a quite old squeakvm 3.8a-1 #1 Sun May  1 19:46:46 EDT 2005 is used.

I have in my plan a Swazoo logger for a while and if someone has a
time... ;) But if you run behind Apache, it is logging Aida requests too?

Yes, that's what I realized later, that due to the proxy pass setup we
can use the apache log.
