]]> Comment on OpenClinica 3.1.3 Community Version – Performance Test on HDD vs. SSD by Janus Engstrøm http://blog.openclinica.com/2013/03/27/openclinica-3-1-3-community-version-performance-test-on-hdd-vs-ssd/#comment-935 Fri, 26 Apr 2013 07:29:51 +0000 http://blog.openclinica.com/?p=1260#comment-935 Thank you for this post,

When comparing OC on installations varying in setup like above, it’s important to be able to differentiate between what kind of load on the hardware that OC is generating: Is the load mainly I/O or CPU intensive?
There has been some speculation on how to speed up OC overall performance by tuning the database, but I still have not seen any data regarding the response time latency introduced by the SQL queries only. As this compare clearly shows, the dataset generation is not a database intensive operation as the performance gain is minimal compared to data entry performance.
IT professionals should of course separate these 2 kinds of load, and if anyone has tried to monitor the server’s CPU load when submitting data entry / loading Subject Matrix / loading Study Subject CRF list / loading a CRF, they have found the CPU to be fully loaded from the time the request is sent to response is generated fully. My guess is that the database load is much less than 1% of the response latency.

It would be interesting to do a more fine grained investigation towards the performance gain when submitting data entry. How much of the gain is due to the *database* being on SSD and how much of gain is due to the *log files* being on SSD… Perhaps Mr. Montri Ridjaibun would like to do the test again with the database files on the SSD only, rest of installation is on the HDD?
