I really like zimbra. In this case I'd use it for myself. I need a few tips to optimize zimbra because currenlty it uses more then 1.5gb ram, without being used at all.
I followed this guide: Making Zimbra run on minimal RAM - Zimbra :: Wiki
But this doesn't help me that much.
Most memory is used by mysql and all the java threads.
I hope to reduce the memory usage, when minimizing the number of java threads. How can this be done?
