tomcat native library

We've all seen the warning in the Tomcat logs: "INFO: The Apache Tomcat Native Library which allows optimal performance was not found ...". I'm aware that this does not indicate an actual problem; in fact I've played with the native library in the past and it didn't change my life, other than that I no longer had to see the message.

However, IIRC the case where the native library is said to really boost performance dramatically is with SSL. Given that Jazz does almost all its work over SSL/TLS connections, is it worth using? Have IBM people derived any metrics with regard to how much it helps, if any? Or is it just the case that SSL performance is not the gating factor? If it does help, has IBM given any thought to bundling it?

Thanks,
MK
