Re: artifactory 2.0.6 speed problems after upgrade

The garbage collection you see is the storage garbage collection and it normally doesn't take more than a couple of seconds, even on a large repository like this one. We suspect that there are JVM major GCs happening while the storage GC is running, which slows it down dramatically. This can be verified by turning on -verbose:gc with -XX:+PrintGCDetails.

I would also suggest putting a minimum on the young gen size -XX:NewSize=128m, as well as trying to increase the total heap.

Having another jmap output to verify that the perm gen issue is fixed is also a good idea.

HTH,

I've made these changes and though the systems seems slightly more
responsive we are still getting regular (twice hourly) alerts from the
monitoring system for slow responses to display the home page.

The log is still showing that the garbage collection is taking 30 minutes in
every hour. Is this normal?

Thanks
