Hi all,
We started an attempt to slice the data we've been collecting in
another way, to show the results of software vs. hardware RAID:
http://wiki.postgresql.org/wiki/HP_ProLiant_DL380_G5_Tuning_Guide#Hardware_vs._Software_Raid
The angle we're trying to show here is the processor utilization and
i/o throughput for a given file system and raid configuration. I
wasn't sure about the best way to present it, so this is how it looks
so far. Click on the results for a chart of the aggregate processor
utilization for the test.
Comments, suggestions, criticisms, et al. welcome.
Regards,
Mark
