Why LSWS slower than Apache 1.3 on my server ?

I already repeated this test with different -n and -c numbers but apache is faster than Lite Speed (standart) at all tests.
For example: with ab -n 1000 -c 1 options, got following results:
with Apache:
Requests per second: 35.84 [#/sec] (mean)
Time per request: 27.91 [ms] (mean)
Time per request: 27.91 [ms] (mean, across all concurrent requests)
Transfer rate: 1252.68 [Kbytes/sec] received
with LSWS:
Requests per second: 33.04 [#/sec] (mean)
Time per request: 30.27 [ms] (mean)
Time per request: 30.27 [ms] (mean, across all concurrent requests)
Transfer rate: 1150.26 [Kbytes/sec] received
I installed LSWS with default options. LS SAPI & TurckMMCache has been installed and php files runs correctly but slower than apache. I'm not using any php accelerator with Apache. (php version is: 4.3.11 with Apache)
What's wrong? What should i do? This server has ~300.000 unique visitors daily and i'm looking for more performance according to Apache..
Thanks
