Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I installed a LAMP server and enabled MySQL remote connections but I'm experiencing really bad response times when connecting to the database remotely from a WordPress install.

I've been looking around for hours for a solution but all I could find had to do with setting "skip-host-cache" and "skip-name-resolve" to true. I've done that and I'm accessing the server via IP, but the problem still persists.

Server Details:

  • Ubuntu 12.04
  • Apache 2.2.22
  • MySQL 5.5.24

There are only a handful of people accessing the server so load isn't an issue either.

I'd really appreciate some help with this.

Can the remote MySQL server resolve DNS? What is the last mile connectivity on each server, –  Ben Lessani - Sonassi Oct 2 '12 at 8:03
The MySQL server shouldn't be doing any DNS resolution because "skip-name-resolve" is set to true. The last mile connectivity on each server is a "standard" business ADSL connection (I'm unsure of the specifics, I'll have to wait until tomorrow to get more detailed information). –  Greg Antowski Oct 2 '12 at 8:48
It still needs to resolve DNS regardless of whether you have set that flag or not. Given its over commodity ADSL connections - its not much of a surprise that its slow. –  Ben Lessani - Sonassi Oct 2 '12 at 9:25
Please define: "slow response". Is connecting slow? Is transferring the data slow? Do the queries take ages to complete? –  Bobby Oct 2 '12 at 10:05
Sadly, I'm starting to think you might be right, sonassi. @Bobby The queries complete very quickly and connecting to the server is fairly fast as well. The slowness seems to come from the actual data transfer. –  Greg Antowski Oct 2 '12 at 10:35
