Hi Marc!
Since we received a message on the users list about this, I made some comparisons between 2.6.0-pl2 and 2.5.4. I am quite surprised to see 2.5.4 being 3-4 times quicker in routine operations like cookie login, changing db, going into Structure page for a table, etc.
Okay, I had that impression as well for quite some time. Nice to see someone verifying this. I suppose the config import stuff and the DB layer, as well as some added regular expression magic may add up to the performance impacts. I am working with xdebug on Serendipity (a blog tool) performance tuning, so I will try to make the same for phpMyAdmin as well :) Regards, Garvin. -- ++ Garvin Hicking | Web-Entwickler [PHP] | www.supergarv.de | ICQ 21392242 ++ Developer of | www.phpMyAdmin.net | www.s9y.org ++ Make me happy | http://wishes.garv.info
