both running at 100MBs

Client and Server were rebooted between the usage of the different servers.

I testet
- Lighttpd 1.3.6, fresh compiled with epoll and "server.max-keep-alive-requests=128"
- Thttpd 2.25b, fresh compiled (with poll?), disabled log-file support
- Boa 0.94.13 fresh compiled with default settings. any kind of log files were disabled
- LiteSpeed 1.5.11 standard, logfiles disabled, without .htaccess or any other security enabled
- litespeed 2.0 standard, logfiles disabled, without .htaccess or any other security enabled, expires disabled, using poll
- dpfTVS 2.0.923 beta, fresh compiled, dynamic pre-fork (go figure)
- dptTVS 2.0.923 beta, based on dpfTVS but uses threads together with the dynamic filecache of hssTVS
- hssTVS 0.176 alpha, fresh compiled with epoll


Performed was a conditonal GET with an additional headerline If-Modified-Since with an exact
matching date/time string. The httperf test gives 3 values(min,avg,max), the average value 
was recorded.

The exact commands were
for non-persistent test:
httperf --hog --server 192.168.0.3 --uri /aeh.gif --port 80 --num-conns 20000 --num-calls 1 --send-buffer 8192 --timeout 5 --add-header "If-Modified-Since: Sun, 07 Nov 2004 10:40:44 GMT\n"''
for persistent test:
httperf --hog --server 192.168.0.3 --uri /aeh.gif --port 80 --num-conns 1000 --num-calls 100 --send-buffer 8192 --timeout 5 --add-header "If-Modified-Since: Sun, 07 Nov 2004 10:40:44 GMT\n"''

All servers answered corectly with a 304 status. Neither Thttpd nor Boa support http/1.1 
persistent connections and closed the connection after the first request, therefor their 
result was not recorded.
