Hi Igor.

I found the solution....

First the benchmark compiled against openssl-0.9.8k

when i configure the stable version 0.7.61 with 

ssl_ciphers  AES256-SHA:1024:256:!ADH;

i got almost the same performance...

Server Software:        nginx/0.7.61
Server Hostname:        192.168.1.97
Server Port:            443         
SSL/TLS Protocol:       TLSv1/SSLv3,AES256-SHA,1024,256

Document Path:          /index.php
Document Length:        4 bytes   

Concurrency Level:      50
Time taken for tests:   3.892 seconds
Complete requests:      5000         
Failed requests:        0

Time per request:       0.778  (mean, across all concurrent requests)
Transfer rate:          277.27  received

PS! i got at least 60% more performance from openssl-0.9.8b to openssl-0.9.8k worth to mention...

Thx for a great product....
