Drupal 7.x

Hello, 

        I run a large D7 website with mysql and solr backend, in AWS EC2.

Until 28th August I had a Debian 6 nginx+phpfpm with APC cache system. My AWS console showed values of VolumeWriteOps at around 50-60 iops, and VolumeReadOps at around 10iops (in this time I had about 30 Internet users).
