So let's see the next part of SSD results - read-write pgbench. Just like in case of a read-only benchmark, the performance of all file systems is almost exactly the same (with the exception of nilfs2, as mentioned later). The average performance looks like this

BTW I forgot to mention one important thing in the previous post - if you're interested in the data collected during the benchmark, I'm ready to provide them. There's one slight inconvenience, though - the HDD results occupy 3.4GB (1GB gzipped), SSD results occupy 38GB (10GB compressed). That's too much to place it to this blog. But if you're going to pgconf.eu in Amsterdam, just ask me ...

In the last few posts I've discussed benchmark results with a traditional SATA drive, now it's time to discuss results of the same tests with a SSD drive (Intel 320). This post is about results of the read-only pgbench test. As expected, the SSD drive performs better than a traditional drive in all three tests, but it's interesting to see how the performance boost varies for various tests and how perfectly are eliminated differences between the file systems.

The average results for all file systems looks like this

The SSD results are available here, comparison of read-only results is here.
