How to Increase the maximum thread count at the Tomcat level In multi-user, high-concurrency environments it pays to tune Tomcat to use more threads to process HTTP requests. Create New Wiki Page. Page Status No Known Problems. Audience Administrator. Servlet no. Reached of connections java. It was extremely interesting for me to read the post. Thanx for it. I like such topics and anything connected to them.
I definitely want to read a bit more soon. Joan Simpson escort agencies dublin. Tried on glassfish 3. When thread pool is large it also causes OutOfMemory on boot time. I am working on windows machine. When i run the above example, it does not create more than connection.
Than i separately tested that on my machine more than threads can be spawned. What changes should i make this example work for around concurrent connection. I have to create a proof of concept for simultaneous connections. Excellent article, it proved very helpful to me as I configure a server that needs to handle a heavy load. My requirment is handle approx. What needs to be configured to handle the mentioned target. PLease comments. It really depends on the service. How much time does one request take?
Is it CPU intensive? Does it wait for disk, network or database? What do you mean by concurrent users? In other words, there is lot of factors you have to take into account, which means I will not be able to help you. The good news is that there is lot of information available on the internet, so I am quite sure you will be able to figure it out. HI I am having application which receives more than request at a time.
Still sometimes i am getting more han 3 digit response time in milliseconds in tomcat logs. Is is because above checks or GC. I am having server with 24 core and 20 gb assign to tomcat. Only 40 concurrent threads served? Their initial setting was Clearly far too high, but even with monitoring we settled on threads to ensure that peak periods do not topple the server.
I have been speaking to some performance experts in-house. There are some other considerations here. There are many asynchronous tasks running by the various applications on the Jazz platform, all of which require their own threads. Indeed, the more registered users there are on the JTS, the more work the synchronizers in particular have to perform.
So, in conclusion. I would then monitor using JMX, again if nothing else is available, to see how this copes during the peak periods. As more users are added and the closer I get to this limit, I would then increment the number of threads in small increments It must be noted that our threads are purposefully designed to stay active for long periods of time to facilitate faster start-up times etc.
This often confuses WAS admins who see in their logs that there are hung threads, when really they are not. In your situation where you are seeing the message, I would increment by no more than and monitor. I hope this helps! I will continue to edit this post as more information is gathered and may convert it to a Wiki article.
I would also like anyone reading this to comment as to whether it helps; whether more information is required to fulfil their desired knowledge need when clicking on this post, etc
