You'll spend a lot of time looking at very large dumps, but you're effectively looking for references that can't get cleaned up. Sam Saffron's writeup on these tools will prove valuable. memory_profiler will then be useful in development to track down those allocations. rbtrace + heapy is your production tool - you can run rbtrace in production, wait for a process to balloon up, and then dump the heap and inspect it with heapy. memory_profiler, rbtrace, and heapy will be valuable here. This has become less important with modern Ruby versions, but you can still get some juice out of it.įifth: When you've run out of easy stuff, it's time to go deeper. is a quick path to this, but there's lot of documentation on these settings out there. You may see immediate gains in both memory usage and application performance as a result.įourth: You can optimize the Rails GC to avoid excessive overallocation. if your on centos then you can be victim of running nginx as httpdt or unconfinedt follow Nginx + Rails + Unicorn Permission Error: sudo nginx vs sudo.

If it's growing consistently, then you need to worry.įirst things first: Consider collecting instrumentation on your RAM usage (and other metrics) with something like Prometheus or Telegraf. If you are a stable 2GB, that's excessive, but it's not going to run you into a hole.

I searched for the best solutions and found out that Unicorn (app server) and Nginx (web server) runs pretty well together. That's why i needed an app server and a web server which works well together for my rails web application.
