Hi there,<div><br></div><div>I&#39;ve been playing around with the pool_of_threads addition and here is some of what I&#39;ve found:</div><div>All of this was on Mac OSX 10.5</div><div><br></div><div>1)  Biggie here:  Running the server with the --extra-port=NNNN option (with pool-of-threads set) causes the server to start then immediately stop.  I&#39;m still looking through logs and trace files to see if I can find anything meaningful.  I am able to run without setting extra-port though.</div>
<div><br></div><div>2)  We can set extra-max-connections when --extra-port isn&#39;t set.  The limit is 100000, at least on my system.  As I haven&#39;t been able to get the server running with extra-port yet, I haven&#39;t tested much beyond this.</div>
<div><br></div><div>3)  We can also set thread-pool-size even if thread-handling isn&#39;t set to pool-of-threads.  It&#39;s limit appears to be &lt; 2560 (I was running into some mess on my system so I haven&#39;t pinpointed it yet).  The biggest thing is that if thread-pool-size is set too large, we just get a start and stop (Once again, my logs are a bit of a mess due to &#39;play&#39;, so I&#39;ll have more info on the server behavior in a bit).</div>
<div><br></div><div>4)  I found that if the number of connections is = thread-pool-size, new connections will terminate within &#39;connect-timeout&#39; seconds (there was some question about whether we had to wait for the denied connection to receive a message until after a thread was freed).</div>
<div><br></div><div>5)  Due to these problems (most especially #1), main.pool_of_threads.test fails on my machine.  If I remove the --extra-port stuff, the test will run more than otherwise (the server dies quickly with extra-port stuff).</div>
<div><br></div><div>For extra-max-connections and thread-pool-size, do we want to allow these to be set even if they aren&#39;t relevant to the way the server is currently running?</div><div><br></div><div>Is there any specific information I can provide if anyone wants to look into why the server dies when I try to use --extra-port?</div>
<div><br></div><div>Testing notes:</div><div>1)  I have some changes to make to pool_of_threads.test (style, additional testing, etc).</div><div>2)  We should also add some testing for extra-max-connections, thread-pool-size, etc.  Possibly to variables.test, though somewhere else would work.  I&#39;ve played around a bit with dynamically changing the variables, etc.  I just can&#39;t get MTR to run the test to really polish my proposed changes before submitting a patch.</div>
<div><br></div><div>Thanks,</div><div>Patrick.</div><div><br></div><div><br></div>
