[jetty-users] seeing slow jetty perf on EC2

[Seth White <seth.white@xxxxxxxxxxxxxx>]

Hi all,

If I run jetty locally (Windows 7 box) and do a simple GET request, I can do 28K requests per second. If I try the same test on an EC2 instance (C3Large) I can only do ~3700 requests per second.   If I try undertow (on EC2) I see nearly 30K request per second.   How can I find the reason for jetty running slow? I've turned on debug logging, but don't see any clues. Could jetty be using the wrong I/O library? Any help would be appreciated.
