[R] my RMySQL connections are so SLOW

Hi all,
I'm using the latest RMySQL to send requests to a MySQL database (which 
is quite small for the time - let's say 20 tables with a total of 1000 
rows), and this should be part of a whole decisionnal system. It 
produces results which are displayed on a website, and therefore I need 
fast results (the database being quite small, I think this must be 
possible !).
Unfortunately, a simple request to the database, and R needs more than 
10 seconds. Even dbListTables() takes a long while. Imagine the problem 
with more data ! Can I hope something better  with RMySQL ? Did anyone 
have the same problem ?
If RMySQL (or is it MySQL's fault ?) is so slow, I could replace MySQL 
with Postgres, but this would imply a lot of extra work. R is perhaps 
very slow anyway ? Any piece of advice ?
