Anyone out there running Linux out there who would be interested willing to share some benchmark research? We are currently on AIX, trying to get an idea of how many add’l processors were required, and if anyone has and brand/gen recommendations. We’re looking at these candidates:
<p style=”font-weight: 400;”><u>AMD Gen 5 Processors:</u></p>
<p style=”font-weight: 400;”>AMD EPYC 9015 – Single or Dual Socket</p>
<p style=”font-weight: 400;”><u>AMD Gen 4 Processors:</u></p>
<p style=”font-weight: 400;”>AMD EPYC 8024P – Single or Dual Socket</p>
<p style=”font-weight: 400;”></p>
<p style=”font-weight: 400;”><u>Intel XEON 6 Processors</u></p>
<p style=”font-weight: 400;”>Intel  Xeon 6714P – Single or Dual Socket</p>
<p style=”font-weight: 400;”>Intel  Xeon 6353P – Single or Dual Socket</p>

We’re in a virtual cluster, we have 8 CPUs allotted for our production box. The CPUs are Intel E5-2697’s.

The clustering system is older and they’ve been talking about upgrading them for some time. Do not know when that is planned.

I think most of your decisions should be based around what kind of load you’re looking at doing, how many million messages you’re processing, etc. We’re a smaller shop and do around 2 million message (all inbound, outbound, site-to-site counted here). RAM,  disk write speed are just as (in some cases more) important than your CPU. Running sar we rarely go below 90% idle, and drops below that are usually us processing a cron job off hours. We’re not fully migrated yet, but I don’t think our CPU usage is going to change that much. Ram, disk speed, etc will change as we’re going to be processing bigger files (getting to migrating the PDFs).
