Does jmxremote affect tomcat performance?
Solution 1:
We monitor CPU usage on our servers(via SNMP) and when we enabled jmxremote to collect stats we did not see a noticeable appreciation in usage(real machines). It looks like someone actually grabbed stats from this and documented it:

They basically say it can vary based on app but saw as high as 5-6% cpu usage increase in some cases.
