[Quake-bugs] [Bug #116066] High and/or spikey CPU utilization with recent beta2

[<no...@so...>]

Bug #116066, was updated on 2000-Oct-04 16:32

Summary: High and/or spikey CPU utilization with recent beta2

Details: This might only be an issue with running multiple ports on a
single box, but I've found that I'm getting high CPU utilization on my
server with this build.  It goes away when I down unused ports, but seems
to return again minutes or hours later.

More details and printscreens of my perfmon graphs are available at:

Let me know if you have any questions, or if I can be of any help testing
this further.

I'm not sure what you mean by "MINGW built bins".  I just downloaded the
"Development Snapshots (updated daily)" and am trying that.  Is that what
you meant?  This is the version that was compiled 12-30-2000 with Borland's
compiler.

Already I can see that a bug that I reported months ago is still evident:
When I start up Clan Arena the server will not assign teams correctly the
first time.  You end up with the players getting a repeating message every
1 or 2 seconds that says "Usage: setingo [ (key) (value) ]", but this seems
to be cleared up if everyone drops and reattaches.  Not sure if the
utilization thing is still evident but I'll report back tomorrow either
way.

Try out latest binaries, including MINGW built bins.

This is still true with beta v5 as well.

As a bit of an update, the CPU spikes happen within an hour or so of
starting up the ports, but only if I have 5 or more ports going on a single
box.  It didn't happen when I only had 3 ports open.  I didn't get the
chance to try it with 4 ports since I had to take it down to get all the
ports going again.  :(

Thanks!

To update (since old bugs are being flushed): This is true with Beta3 as
well.

To give a little more info on this, you start out with CPU utilization
being fine, but after a bit of time or usage it turns spikey.  The only way
to get it calmed down is to remove some or most of the ports.  It's
probably fine if you don't run multiple ports, or if you only run 2 or 3
ports.  But it messes up with the 5 or 6 ports that I run, which is
definately not the case with the standard QW server.

DOH!  One more thing that you have to know when looking at my print screens
is that I'm running the distributed.net client so utilization would
normally always be at 100%.  To make it so that I can see how much
utilization is being used by processes other than the distributed.net
client I told perfmon to monitor the CPU utilization of the distributed.net
client.  Therefore, if it's at 100% then all CPU is dedicated to DNETC.EXE.
 IF it's at 90% then something other than DNETC.EXE is using 10% of the
CPU.

So, think of it as being an upside down CPU graph.  :)  The lower the
graph, the more CPU is taken by processes other than DNETC.EXE.

I've now included some additional information (including the above
explanation), including screenshots this morning when utilization was all
over the place even with zero players.  It all calmed down when I took down
the Matador port.  So, now I've reset the PC and restarted all ports except
for Matador to see if things still mess up or if it's something that can be
traced to Matador.

Sorry, I didn't have an account set up so you didn't know how to contact
me.  This one is now done with me logged in.  :)
