If you want to see where this latency limit is before you reach it in
production, try using Julian's testlvs - http://www.ssi.bg/~ja/#testlvs,
perhaps along with apachebench (ab). I will bet you 3 to 1 that your real
servers fall on their faces before LVS. Hopefully you will pay for me to go
to Cabo and fish some marlins :)
PS - how did you solve your 'email when servers IS/OOS' problem?
