Hey,
not sure how you can survive with superserver :)
I can't see that working with our kind of load (realtime-data-processing,
reports, mostly write IOPS)
It's a long time ago (Fb 1.5) since we used superserver but we didn't have the
best time with it back then.
But currently this is not about
Hi,
just curious – why not superserver?
I do not know what your system do and if it is cpu intensive –
but i always use superserver because of big cache and this is for me biggest
speed up.
I use superserver in environment with ~400 connections (near constant) and high
load without problem.

Hi Patrick,
If you say that problem occurred recently, I would suggest you to check
SAN disks health.
However, these values
Average system IOPS under load read: 100
