[CentOS] mod_gnutls on Centos 4

Hi,
as you might know I have created mod_gnutls for CentOS4 a few months ago.

I'd like to ask if someone is using it? It seems to me that it's not
able to handle higher load. When user hits F5 there are a few httpd
processes running the full cpu. Strace shows nothing, server-status
marks them "reading". :o( It seems to me that when user breaks/stops the
request httpd breaks. Any experiences?
Thanks,
David
