[Lift] Re: lift stress tests and comet
David, Many thanks for the quick response. Is the test set up available anywhere? i'd like to see what the major differences are. We're using comet with Jetty.

[Lift] Re: lift stress tests and comet
Greg, It was buy a feature proprietary code... so it's not available. Lemme see if I can set something up. I did notice that with a recent version of jetty, I was seeing a 50% failiure rate when saturating the server with std http requested... switched to tomcat and the issue went away. I spent time with greg wilkins of jetty fame at javaone. I feel very confident that greg will address any issues that we run across.

David, Btw, i don't see a use of the Bayeux lib in lift, but want to double check that it's not being used.

[Lift] Re: lift stress tests and comet
It's not. We rolled our own comet pre bayeux... and our stuff is still better for multiple open browser tabs.
