What are some tweaks you guys do to optimize your EngineX servers?

I've enabled gzip compression, is there anything else I can do?

My sites are predominantly WordPress-based.

Perhaps these:

   server_tokens off;
   worker_processes   2; # try -> grep -c processor /proc/cpuinfo
   worker_connections 1024;
   keepalive_timeout   10;
   send_timeout      12;
   sendfile        on;
   tcp_nodelay        on;
   gzip  on;
   gzip_min_length 640;
   gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;
