We're running a virtual set-up on a private cloud - with a physical capacity of 48 cores and 384 GB RAM. 4 x 128GB SSDs in Raid 10 for the DB. The virtual layout includes 8 webservers, a couple of varnish servers, a couple of memcache servers, plus one master and two slave DB's and we devolve search to Solr. We've had the guys from Percona fine tune the DB's and queries.

We're doing a bit more work on Memcache and Varnish optimisation, but feeling we're likely to yield more from front end optimisation now.

Have you tried running NewRelic or Dynatrace on your backend? At your scale it's probably something you want to leave running all the time (rather than just for a quick trial) but it will tell you where your hotspots are for the backend (specific database calls, etc).

It does sound like a well though-out back-end (a little surprised the times are not better).

I'll take another look at the front-end (particularly repeat view) in a minute.
