I don't know what hardware we'd choose, but I wholeheartdly agree on
the need for some better hardware than what we have now.
During afternoon (french time), it becomes slow as hell, painful to
see Wikipedia crawl like that... -.-
Buying more and more hardware isn't always the best solution,
especially not when "it's slow" is all you know.

It would be useful to have MRTG or similar graphs available for _all_
the servers in the cluster, showing for each system:
* disk I/O seeks/second
* disk I/O bytes/second
* network interfaces bytes/second
* CPU load
* memory usage
* swap load
This, in conjunction with the existing real-time performance graphs,
would enable "many eyes" to inspect the system, and form hypotheses
about where the bottlenecks are.
