Doing dbt2 tests on on the intel drive today… One of the strange things I ran into last time testing out my memoright drive was running the RPM version of the enterprise binaries -vs- the tarball version seemed significantly faster. I had some other folks try it on other hardware and they could never replicate the performance slowdown,. Basically before I was getting 4407 TPM in DBT2 from the RPM (5.0.60) in Centos 5, while the tarball (5.0.60) was only hitting 2505 TPM. This was consistant. Now I see that my most recent run of dbt2 against the Intel SSD acheived 3600 TPM/s, which is lower then the rpm, but higher then the tarball ( this was achieved via tarball ). As i said this difference has not been verified independently, and it could be any number of odd factors at play on my hardware.
I need to go back and figure this out again… But on a positve note, apples to apples the intel ssd …[Read more]
