strange delays with ssl

Hey,

I'm experiencing some weird thing with Haproxy. I'm new to it, so I hope that you guys will figure this one out in no time :). Here it goes:

I configured Haproxy to do TCP load balancing. That's because I'm balancing HTTP+SSL traffic and my traffic may be too heavy to decipher it on one machine. So the SSL traffic gets forwarded to the backends, they do their job, send the response back, everything's fine. One problem though: It takes too long! It's like 3.5 seconds per one request. My backends are also visible to the Internet and if I talk to the backend directly, I get the response in no time. So something is definitely wrong here. What is really interesting is that if I talk to Haproxy on port 443 and send plain HTTP request (via netcat), I get the response from backend immediately. The response says that I sent plain HTTP request to HTTP+SSL, but never mind. And what's even more interesting, I can't find noone else who would experience such delays. It seems that the issue is only related to my computer and my SSL client library. But I'm worried that my users may also experience such thing. Any idea, what may be wrong? Below is my Haproxy config.

Regards,

Mike
