general - Apache2.2 Max Request

Good day to all,

Does anybody know Apache2.2 WinNT MPM can handle up to maximum how many request concurrently?

My current setting on httpd-mpm.conf as below:-
# WinNT MPM
<IfModule mpm_winnt_module>
ThreadsPerChild 4000
MaxRequestsPerChild 0
</IfModule>

But, when I check on apache server-status link, it show up to 1920 workers only. I suppose it should show 4000 workers, so is this (1920 workers) max limit?

My case need to support up to 4000 request at the peak hour. Appreciate if any advice?

Thanks.
