[ut3] CPU Usage 32bit intel <> 64bit amd difference

[Ken Shelton]

I have a Intel xeon  bit dual core on red hat enterprise 4 64 bit OS - and
it is using high resources

Since I don't have such high CPU utilization on my 64-bit Intel server I'd
look into it being a possible problem on the AMD systems.

I finally got to setup the UT3 server on some of my dual xeon machines the
weekend, and was fearing to have to relocate servers as the CPU usage I
noticed thusfar was insane.

My dual AMD Opteron (2,2GHz, 4GB Ram) running 64bit Gentoo eats 50% when the
server is IDLE, thus not able to run more than two instances. Now I
discovered that on my dual Xeon (2,8GHz old Prestonia 533MHz FSB) and Dual
Core Pentium-D (3,2GHz) it eats 3% and 1# respectively (prolly caused mostly
by the first running 500HZ mode, other 300HZ).

 

Have you seen, or do you have any idea what might be causing the Ryan, is it
AMD<>Intel or rather 64bit<>32bit?

 

Kernels on the boxes (Opteron <> Xeon) are identical, apart from 32bit <>
64bit NUMA. 32bit boxes run slackware, 64bit one is gentoo, but all relevant
libs are at the same levels. Would love to know what to 'avoid' for other
servers, and lack options to test 32bit on the opteron, nor 64bit intel at
this time.

 

Any heads up would be greatly appreciated!

 

 

Greet and do enjoy your Christmas and such and get back on this next year ;)

P.S. Had you been able to look at some 'ServerReadStdIn' alike function?
