We've ordered a new cluster of 3 servers, each with two Dual-Core Opteron processors and high-speed SATA hard drives. Soon, ATS will be back to
"smokin' speed". One of these monster-servers (with 4 gigs of ram) will be dedicated completely to serving just the ATS board (we're not yet ready
to jump to the overhead and expense of load balancing).
However: As traffic will only continue to increase, we're also looking at ways to optimize our current code base (again). Among the extra
loads are the additional database look-ups needed to display your custom backgrounds (especially on longish threads). For now, this feature is
disabled while I monitor the impact on the servers.
U2U Notice: We'll also be looking at things like u2u in-box totals. Right now it only displays your most recent 25 received U2U's, also as a
performance test... if you want to see older U2U's, either delete current ones, or move them to your saved folder (no display limit). We may end up
limiting how many U2U messages you can retain in your inbox (it's complex, but the inbox total effects system performance more than the others since
it's "looked at" every time you load a page, and listed every time to hit the memCenter).
We regularly experience over 60,000 visitors a day and about 180 database queries a second with our current stressed-out server cluster. I
fully expect a new traffic surge once the improved cluster is online and giving ATS a new performance boost. So we need to make sure that overall
functionality is preserved throughout the next round of high-traffic issues (our likely next milestone of concern is around 120,000 daily visitors).
