--- Comment #19 from Martin Steigerwald <mar...@lichtvoll.de> --- Gunter, how big is your sent folder? How many mails are in there. And, I am not sure whether it has been mentioned already, but my better experience may (!) be related to some manual MySQL tuning. Especially: # memory buffer InnoDB uses to cache data and indexes of its tables (default:128M) # Larger values means less I/O innodb_buffer_pool_size=1024M I have no scientific measurement, but I think I noticed slowdowns as after an upgrade of Akonadi its replaced that file with a newer one. I made a bug report about this quite some time ago, but the a dev declined my suggestion to raise the ridiculously low 64M I think default to something higher with the argument the configuration came from I think Kristian Köhntopp so it must be right. Also, and I get that, there are smaller mail setups as well. From what I understand about MySQL performance tuning, the default value set by Akonadi MySQL standard config is way to low for larger setups. mysqltuner.pl agrees there as well. I suggest you run mysqltuner against the socket of the Akonadi database and then review the suggestions it makes. I am pretty sure it will tell you to raise the InnoDB buffer pool size considerably. -- You are receiving this mail because: You are watching all bug changes.
