Hi,
What is the pro and con to set up pagefile on a strip-set of 2-3 disk
for OVMS 6.2 1h3? The AlphaServer 4100 cluster has 4GB memory on each
member.
I believe it will improve performance if there is any paging I/O ( on
the other hand, we try to reduce the hard page fault as much as
possible)
Thanks,
Patrick

I'd first determine where the performance is being spent, and
look for indications of where the present limits are...
I'd add usually add more memory first... If the configuration is
maxed out, there's no reason not to move the pagefile to a stripeset,
but with the understanding that this configuration arguably increases
the exposure to disk failures. I'd also look at spreading the
pagefiles across spindles and I/O channels, as this can also reduce
"hot-spots" in the system.
You will be moving the secondary pagefiles only, unless you are using
a controller-based stripeset... (Obviously...)
