Using Jira on a dedicated Tomcat instance on a 4-way RHEL server with 4GB RAM. With increasing traffic, what is the maximum concurrent request capacity seen in similar setups?
Based on personal experience with similar configurations, a deployment on a 4-core RHEL server with 4GB RAM running Jira on Tomcat typically copes with about 50 to 70 concurrent lightweight requests under default settings. This figure can be influenced by factors such as the complexity of transactions, indexing operations, and the responsiveness of the backend database. I encountered that after this range, response times tend to degrade noticeably. Adjusting JVM parameters and enabling caching might push the threshold further, yet in most practical scenarios it is advisable to consider clustering or scaling strategies for significantly higher concurrency.
