http://www.paessler.com/blog/2009/04/06/prtg-7/monitoring-cloud-computing-performance-with-prtg-cpu-disk-memory-speed-comparison-of-amazon-ec2-instance-types/ Confirms what was noted elsewhere: EC2 small instance is not worth the money, it performs several times slower than medium or large instances
http://www.thebitsource.com/featured-posts/rackspace-cloud-servers-versus-amazon-ec2-performance-analysis/ Testing amazon and rackspace instances: kernel compile time and “how much it costs to compile kernel on $instance”, and IO tests using IOzone – in short: rackspace is cheaper/better, about 2x on average across the board. Note about “m1.small” i.e. small ec2 instance – performance sux, and it is actually cheaper to use a more expensive instance, “medium - cpu” or c1.medium.

http://nuclight.livejournal.com/125747.html A way to detect BT protocol traffic – instead of looking at every packet, traffic to torrent tracker websites is redirected (via divert(4) ) and then analyzed. Analyzer script (PERL) produces the src_ip, dst_ip, dst_port triplet, this info can be used to produce firewall rules
