[Phpmyadmin-devel] Solution for poor performance due to querying information_schema
Hi Devs, As a possible solution to slowness faced by database servers with thousands of databases due to the usage of information_schema [1], I have started working on putting back the 'DisableIS' configuration. What I did so far can be found at [2]. I will update on the progress.

I feel that the pull request [3] for this issue is ready to merge. I've tested on a server having more than 5000 databases with DisableIS set to true and the performance is quite acceptable.

Great. I suggest to merge, then you could ask J.M. for credentials on his test server (which points to master) with more databases (or I can share with Madhura the credentials that J.M. gave me). -- Marc Delisle (phpMyAdmin)
