Thanks guys for the input.
It was between the www servers and the MySQL + JPGs server. We asked
the hoster to add a filer, and performance is much better now, with
the filter being shared between two Apache servers
If demande keeps rising, I guess we'll have to investigate MySQL
clusters, so that the DB doesn't become the bottleneck again.

Yes, that's what I suspected :-/ So I guess the standard solution to
scaling databases is to add some kind of load balancer, and 2 or more
DB servers behind it. |
