Greetings,
I've been asked for help regarding a site on a shared hosting provider
(MediaTemple). Recently the owner received an email indicating
"..Today our automated systems checked your database activity again
and determined your activity continues to exceed the MySQL SmartPool
v.2 resources included with your Grid-Server..."
Caching is on (normal) as is block caching and the other options
available in the performance menu. I've turned up the minimum cache
lifetime to an hour -- there is a fair amount of traffic but the
content is relatively static. I've never had the "problem" of too
much traffic before, and I am not sure what tools are available to
attempt to minimize this, nor am I positive when how to evaluate when
resources are at their limit and it's simply best to upgrade the
server resources ... so I'm wondering if anyone would have any
suggestions or tools or tips on this?
I'll paste the included MySQL report below, in case that information
is helpful. Thanks,
Brian
