First of all, big thanks to everyone contributing to this project --
this is a truly cool idea and it's helping our site performance a hell
of a lot. <br>
<br>
I'm currently running 10 3ghz Xeon machines with -- temporarily -- a
gig of ram each on the 2.4 kernel. My concern is that I'm seeing an
average of about 40% system cpu usage with only 2% usermode usage.
Looking at the stats, each box is being hit at roughly 1100 get/set
requests a second and reading about 71kb/s while writing 361kb/s.
Would moving to 2.6 reduce cpu load? Turning off hyperthreading? <br>
<br>
What kind of hardware are you guys running? We're looking to move to 64
bit AMD systems.. Should we consider dual cpu or will it not improve
access time significantly? Whats the sweet spot for amount of RAM per
box?<br>
<br>
Any thoughts or links to performance studies would be greatly appreciated. Thanks in advance!<br>
<br>
