Speed problem downloading large file

[user3]

Hello,

I have tested the speed of the web server using ab.
Really, litespeed is faster than apache as my ab test.
But the result was not good against large file download.

At this site(http://www.litespeedtech.com/benchmark.html),
Just tested small size file.

Anyone who have tested larger file(over 1M) download speed test?
The result was like below.

Apache 2.2 is 2~3 times faster than litespeed.

-> there is no limit(bandwidth, conneciton..) at configuration file.
and I have tested at a server which have different port number.
from local and remote, but the result was same.

apache 2.2 : 80
litespeed : 8080
