this can be controlled as following:

setting the system property/env var to “lucee.request.limit.concurrent.maxnormprio=5“ / ”LUCEE_REQUEST_LIMIT_CONCURRENT_MAXNORMPRIO=5”, if now more than 4 request having the same remote ip, Lucee will reduce the thread priority of this this.

setting the system property/env var to “lucee.request.limit.concurrent.maxnosleep=20“ / ”LUCEE_REQUEST_LIMIT_CONCURRENT_MAXNOSLEEP=20”, if now more than 19 request having the same remote ip, Lucee will force a nap on every new request, before starting execution. nap time is defined in ms with system property/env var to “lucee.request.limit.concurrent.sleeptime=100“ / ”LUCEE_REQUEST_LIMIT_CONCURRENT_SLEEPTIME=100

 

Good thing about this changes, it will not disrupt any existing code that has this feature enabled, because it does not block any request. Same way Lucee reduces prio of threads running more than 10 seconds.
