My response to "Maybe not enough?" is "it might be too much" if you're  
setting aside more RAM than your system has free for MySQL, you could  
be using SWAP which would have the opposite effect. You need to decide  
if you're using swap and adjust your memory allocation accordingly.

If you are swapping, there will be a delay when you switch from RAM to  
swap. There might be network issues happening if your frontend is not  
on the same machine as your backend. Basically, there are TONS of  
variables when talking about something taking longer than expected, so  
I'm just throwing out the common ones.
