There is no definitive answer to this question - at all. how many threads the OS allows tomcat to allocate.request answering time (duration of request handling - that's your application).According to the Java virtual machine specification, the JVM divides the memory into: Where new and tenured belong to the heap memory, and the heap memory will start the parameter (- Xmx:3G. 1 JVM memory model and garbage collection algorithm. Network connections: If all clients connect through very slow networks, they'll keep the connections open for longer Summary of JVM garbage collection and performance tuning. Three core components of ZCS (a) the Java based message store (aka mailbox server, jetty in ZCS 5.0 onwards, tomcat in 4.5.x and earlier), (b) MariaDB (MySQL prior to ZCS 8.5) instances used for metadata, and (c) LDAP servers (master and replica) - all rely heavily on caching data in RAM to provide better performance and reduce disk IO.Memory and Garbage Collector settings for your JVM.
#Tomcat 8 performance tuning install#
Install tomcat from (and dont use Ubuntu apt-get install). Available memory (and use of virtual memory in the OS) It will improve search performance on OpenMRS 1.7.4+, 1.8.4, 1.9.1+, 1.10+.All these activities of course only, if your measures show that this fixes the bottleneck you found during debugging.īringing in the points from my comment: This is what it depends on (incomplete list) - even if you'd answer every single bullet point, it'll still be impossible to predict a number: Then raise or lower the number or accepted connections according to your measures.

Ask Question Asked 5 years, 6 months ago. Some applications are CPU-heavy, others are limited by RAM, or DB performance or I/O. This topic includes tomcat startup boost & performance optimization, JVM & GC configuration, and some customizations dedicated to Magnolia. tomcat 8.0.32 - Performance Tuning in Server.xml configuration in production server. You know best what your application does, and you know what hardware your server has. The maxConnections has relationship with maxThreads, and you should configure.tomcat 8.0.32 - Performance Tuning in. The maximum number of connections that tomcat can access - just as the number of concurrent users - fully depends on what your application is doing: It might calculate fractal images for every single request, or it might just show static content.
