Brief post-install update. After a “regular” system update forced a reboot, all of the services mentioned (that did not start correctly after the distribution upgrade) restarted just fine.

There were 56 updates today, and after restarting (it said it must), I checked the vitals, and all was fine.

Have you noticed any performance hit on the MySQL 5.5 upgrade? SELECTs seem ok, but I have a few apps that are an order of magnitude slower (MyISAM or InnoDB), approx 30x slower.

For now I’ve spun up a 10.04 server VM running MySQL 5.0 along with an stunnel from localhost:mysql to VM:mysql.

I’ve been able to reproduce this on a few different machines, so I’d be curious to see if others notice it as well.

I’ve not noticed anything, especially on the scale of thirty times slower! I’m running this blog, a few other copies of this blog software (for other domains), a black-hole e-mail web app, and a half-dozen other web apps written by others. Additionally, the database is completely dumped twice a day for back-up purposes. No one is complaining about the performance, and none of the automated processes seem to be taking any longer than usual.

I wonder if your experience isn’t from being inside a VM or tunneling into the VM. Why not just open the VM’s MySQL to accept connections from the VM network, and connect directly?
