Hi, Christopher I don't care if the threads will be reduced, I just want to know why. And we want to use the account to determine when the tomcat capacity is not enough that we need to add max configuration or add new tomcat servers.
Since not use the <Executor>, the busy thread account also cannot tell us the correct active threads count. In another email thread, you said if use <Executor>, it will tell us the right active thread count not just busy count, right? -smith -----Original Message----- From: Christopher Schultz [mailto:ch...@christopherschultz.net] Sent: Wednesday, January 18, 2017 3:28 PM To: Tomcat Users List Subject: Re: FW: tomcat 8080 thread not reduced -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Smith, On 1/18/17 12:47 AM, smith wrote: > So the tomcat default executor will not reduce the thread count until > it reach to the max configuration? By default, you get a thread pool that isn't as smart as an executor. > Will it reduce when it reach to max? Not unless you use an <Executor>. > And why the default not reduce the thread? Because it didn't do so in the past, before <Executor> was introduced. I'm curious: if you are willing to have e.g. 200 threads available at any time during the life of the JVM, why does it matter if those threads are reduced during times of inactivity? I think of threads as a resource like memory, where if you are going to allocate X resources, you may as well allocate X resources and be done with it. Growing and shrinking pools of things just adds complexity and reduces performance. Idle threads are "free" other than using a little bit of memory. So why is it so important for those threads to stop when they don't have any work for a while? - -chris > -----Original Message----- From: Christopher Schultz > [mailto:ch...@christopherschultz.net] Sent: Tuesday, January 17, > 2017 7:18 PM To: Tomcat Users List Subject: Re: FW: tomcat 8080 thread > not reduced > > Smith, > > On 1/16/17 8:22 PM, smith wrote: >> Yes, I think thread count should be reduced when those threads are >> idle > >> Is this right?
