After doing some reading it seems like Nginx might perform better with static content and many concurrent users/requests. I believe Jira doesn't have many static content and we have ~200 users.
Does anyone have experience with replacing Apache+Jira with Nginx+Jira or with Nginx+Apache+Jira?
In case you do, why did you do it and was there any performance improvement?
I've seen this done on several servers, and the answer is a very clear "maybe". In a couple of places, the metrics came out at "negligble change", one place took a performance hit of around 30% on page loads, and another one saw a 30% improvement.
I think it's important to look at why you're doing it, and most importantly, what your internal support teams support better.
