Are there any docs that reference performance differences between 2.6/7 and 3.1? I'm running several 2.6 clusters (forward proxy) with all caching disabled doing 20-30mbps per node. The nodes are not far from idle in terms of CPU and memory. They are currently running RHEL5/x86_64. Should I expect to see similar performance on 3.1, or even better? Thanks, Josh
