I did some informal investigation by watching the system load and didn't notice much of a difference. The postgresql process sat at about 10-12% under all conditions. I think this was another effect of the lack of parallelization in my tests. Had the test been hitting the database with many simultaneous queries, the addition of memcached would probably have a noticeable effect. It's also worth noting that Grails ate up most of the available CPU anyway. Good question, Sven. I did some informal investigation by watching the system load and didn’t notice much of a difference.

I am curious to see if you investigated teh load on the DB server, which is for me the primary reason to used memcached. I would assume using either local or remote memcached, it dramatically reduces the load when doing loads (and should be stable for inserts, e.g. the same as without memcached). Cheers Sven Hi Tim,

nice blog post. I am curious to see if you investigated teh load on the DB server, which is for me the primary reason to used memcached. I would assume using either local or remote memcached, it dramatically reduces the load when doing loads (and should be stable for inserts, e.g. the same as without memcached).

I scribbled the steps from memory and of course I remembered it wrong. Fixed to reference the jar instead of the imaginary plugin. Thanks! Thanks also for pointing out the domain object caching configuration. Duly updated. Doh! I scribbled the steps from memory and of course I remembered it wrong.

Thanks also for pointing out the domain object caching configuration. Duly updated.
