http://haproxy.1wt.eu/10g.html HA Proxy [synthetic] benchmarks on 10Gbit traffic. Linux network stack is the bottle neck here, not HAProxy, i.e. you can 10G line rate on big frames and few connections.

http://vbtechsupport.com/606/ Sysbench-based benchmark comparing OLTP workloads for different builds and forks of MySQL on 64-core intel machine (Quad Intel Xeon L7555 ) . Only one definitive result is that MySQL cannot scale beyond 8 or 16 cores, or in some cases beyond just 2 cores (booo! ). In all cases performance went down when more than 24 cores were used .

http://www.facebook.com/notes/facebook-engineering/real-world-web-application-benchmarking/203367363919 Facebook has build custom web-app testing framework to test server performance. Read it, especially the section on why “standard” SPECxxx benchmarks are not a good measure of anything. Also, ready about performance-per-watt, as this is really important for modern data centers.
