Ask HN: What QPS does your application/hardware stack get?

Inspired by the performance number of Mysql/NoSql article. I started wondering what QPS people are getting on their complete application stacks(frameworks->lang->persistence->hardware).

QPS are hard things to calculate unless you actually implement the full solutions. HN is supposed to get "350k pageviews" build on Arc/MzScheme with hardware: "Old: 2.4 GHz Pentium 4, 4 GB RAM, 32-bit FreeBSD 5.3. New: 3.0 GHz Core whatever, 12 GB RAM, 64-bit FreeBSD 7.1." from posts about 2 years old

My last startups got 10k QPS for a Adserver profile tracker running Mod_Perl->Apache2 over a GDBM datastore on CentOS 5.1 Linux Server with 2 x Quad Core Xeon E5410 2.33 GHz, 4 GB RAM 2 x 80 GB SATA @ 7,200 RPM

What QPS are you getting on your RoR/Seaside/php/JavaSpring web site/app/service?
