RE: Tomcat 8/NIO performance discrepancies

Thanks, Mark. Here are some additional details. I am using Apache JMeter to inject load. I am using a simple hello-world JSP. The test JMX simulates 100 concurrent user threads with a ramp-up of 5 secs and uses an HTTP Cookie Manager, that reuses cookies for each user thread. I have disabled

Re: Change of status code for ClientAbortExceptions - bug?

Is there some way to avoid having it logged as a 500 in the access log then? ClientAbortExceptions are so frequent that it really pollutes the access logs, drowns out 500s actually caused by the server side application, and makes monitoring and debugging based on the access logging a lot
