I'm intermittently experiencing severe performance drops due to Java garbage collection. I'm allocating a lot of RAM to my Java process (27GB of the 32GB physically available). Under heavy load, the performance drops approximately every 10 minutes, and the drop lasts for 30-40 seconds. This coincides with the size of the old generation heap dropping from ~27GB to ~6GB.
Is there a way to reduce the impact of garbage collection? A couple ideas we've come up with (but haven't tried yet) are: increasing the minimum heap size, more frequent (but hopefully less costly) garbage collection.
