You might be running into the maximum number of threads for Tomcat's default connector. The NIO connector should be able to work around that.
In general, I don't recommend using one browser as a means of load testing. If you want to get a good idea of how many connections your server can handle, the load test will need to use independent machines such that the browser itself does not taint the results. http://mail-archives.apache.org/mod_mbox/guacamole-user/201803.mbox/%3CCALKeL-Oc6xnj99D9G9mE3aAS1Bj6xL%3DRnCM%3D052VCeMn%3DdBs9g%40mail.gmail.com%3E http://mail-archives.apache.org/mod_mbox/guacamole-user/201803.mbox/%3CCALKeL-PN9hX1KgQ1ktsh600M3i2_sKRyKCx1yc3JyPXuS%3D968g%40mail.gmail.com%3E - Mike On Wed, Jul 25, 2018, 10:43 McRoy, Jeffrey (GE Healthcare) < [email protected]> wrote: > Hi Everyone, > > > > I was using the simple Guacamole example client to attempt some load > testing and got the following results.
