We use haproxy and EC2 instances as load balancers for our clusters. The tuning we use is pretty standard (somaxconn, nf_conntrack_max, tcp_fin_timeout, rmem_max, wmem_max and etc) running vanilla ubuntu AMIs. While EC2's instances and network have performance problems it is possible to get r

Tuning HAProxy on EC2 instances?

2010-01-31 Thread Alexander Staubo
Has anyone any experience tuning HAProxy for performance when running on Amazon EC2 instances? For example, are there any kernel parameters that should be tuned differently, or are some instance types better than others? Does HAProxy generally perform well on EC2?
