| Apache very slow since OpenSSL activated

I recently enabled openSSL on my Windows Apache 2.0 installation. I have PHP 5.1.4 installed and the openSSL version is also 5.1.4. Since I did this, my http requests have become extremely slow and in most cases would result in unable to connect error.
I disabled the OpenSSL module in the php.ini and the server is now working perfectly again.
I need OpenSSL but not with this sort of side effects. Also, there is no errors in the apache logs.
Anyone have any suggestions as to what it could be?
Thanks

A rule of thumb: SSL will make your site about 3x slower.
More or less.
That's a stat that a sysadmin once told me. I'm inclined to say that's a conservative estimate.
As the server is working 3x harder to decrypt all the requests, consequently your server will be able to handle 33% of its usual load.
Watch your CPU usage when SSL is turned on. Maybe you just need to throw more hardware at the problem.

I recommend you try the Apache 2.2.x distro instead.
| openSSL version is also 5.1.4 |

Actually, that's probably mod_ssl, not OpenSSL. And PHP is likely 5.2.14. Here nor there.
I had issues with Apache > 2.2.14 on our Windows test server so reverted to 2.2.14, haven't tried the latest 2.2.17 release yet. But maybe give that a shot first?
