Poor #requests/second performance

[Andreas Jung]

Running Varnish 2.0.4 on a Debian installation (dual-core, 2.8 GHz).

Apache-Bench gives me a performance of 500-600 requests/second against
a cached HTML page - even with an almost empty VCL configuration file.

Squid gives me about 4000 requests/second on the same cached page.

What is the best approach for narrowing down the bottleneck?

Andreas
