[Linux-HA] Should We Upgrade from 2.0.4?

[Robinson, Eric]

>worth mentioning however, is the performance improvements in .8 (when
it comes out).

Right now, my active database server (dual-core, dual processor Xeon)
runs at <2% CPU utilization on average. I don't expect the workload to
really tax it for another 1-2 years at our current rate of growth. By
then we'll be ready to purchase a 16-core monster. :-)

The only thing that does not work properly is STONITH, but I can live
with that because we use DRBD with a shared-nothing architecture, so
STONITH failure is not a real show stopper. (Works fine from a shell
prompt, but when I use it from heartbeat, I get errors. No luck figuring
out why.)

My active LVS load-balancer (single-core Celeron) runs at about 2-5% CPU
on average.

Bottom line is that I probably would not benefit from the extra
heartbeat performance right now. Thanks for the feedback, though.
