Being skeptical is the best approach in the absence of verifiable/falsifiable data. Today or tomorrow I'll get my hands on a new host system and although it is supposed to go into production immediately I will probably find some time to do some rudimentary benchmarking in that regard to see if this is worth investigating further. Right now I'm
That sounds great. I've got a machine coming online in the next few days as well and will do some testing on there. Its got 2 of these :
Intel(R) Xeon(R) CPU E5310
So not the newest/greatest, but should be fairly representative.
planning to use fio for block device measurements but don't know any decent (and uncomplicated) network i/o benchmarking tools. Any ideas what tools I could use to quickly get some useful data on this from the machine?
iozone and openssl speed tests are always a good thing to run as a 'warm up' to your app level testing. Since pgtest has been posted here already, I'd say that is definitely one thing to include so it creates a level of common-code-testing and comparison. mysql-bench is worth hitting as well. I have a personal interest in web app delivery, so a apache-bench hosted from an external machine hitting domU's / VM's ( but more than 1 instance, and hitting more than 1 VM / domU at the same time ) would be good to have as well.
And yes, publish lots of machine details and also details on the code / platform / versions used. I will try to do the same ( but will limit my testing to whats already available in the distro )
thanks
