Tomcat Connector Benchmark

2005-07-12 Thread Vicenc Beltran Querol
Hi, I would like to know if there is an official benchmark to compare the scalability/throughput of the new connectors (APR, Grizzly, ...) and Coyote. If not, maybe it's a good time to define one. Regards, Vicenç - To

Hi, The results of the AB benchmark configured with 20 concurrent clients are posted below, If somebody is interested in more configurations (from 20 to 1 concurrent clients) they are available at http://www.bsc.es/edragon/pdf/TestAb.tgz BTW, there is also available a comparison between

Hi, The APR connector has a trick to optimize pipelining (where a client would do many requests on a single connection, but with a small delay between requests - typically, it would happen when getting lots of images from a website). What's the trick? Are you trying to do blocking read

Hi, I've repeated the tests on the hybrid architecture using the AB. You can find them attached to this mail. I've run the AB with several concurrency levels, ranging from 20 to 1. You can see all the results in a plot. Running a test with ab (ab -k -c 20 -n 2

Hi guys, I'm not trying to be a Tomcat developer. I'm working on my PhD on web performance and just decided to share with you the experimental code I've developed after studying the performance obtained ;). Anyway, it's OK. I'll work on the new patch and resubmit it. Thanks for the comments,
