Simple SSL Perfomance Comparison

Command used to test:

# openssl s_time -connect localhost:$PORT -new

Tomcat APR/Native:
2011 connections in 10.67s; 188.47 connections/user sec, bytes read 0
2011 connections in 31 real seconds, 0 bytes read per connection

JBoss Java connector:
460 connections in 11.01s; 41.78 connections/user sec, bytes read 0
460 connections in 31 real seconds, 0 bytes read per connection

Apache:
2753 connections in 14.43s; 190.78 connections/user sec, bytes read 0
2753 connections in 31 real seconds, 0 bytes read per connection

Weblogic:
797 connections in 3.81s; 209.19 connections/user sec, bytes read 0
797 connections in 31 real seconds, 0 bytes read per connection

Conclusion:

  1. Using APR/Native is better for performance.
  2. Weblogic is quite OK, performance better than JBoss, considering that it is using JDK 6 (will try with JDK 7 & 8 later).

Updates (26 Oct 2016)

Weblogic + JDK 7
1103 connections in 2.86s; 385.66 connections/user sec, bytes read 0
1103 connections in 31 real seconds, 0 bytes read per connection

Weblogic + JDK 8
889 connections in 4.27s; 208.20 connections/user sec, bytes read 0
889 connections in 31 real seconds, 0 bytes read per connection
