Java - issue with memory

Question

Need some help from the experts!

We have a project here (still on dev) that needs to run 50 java processes (for now and it will probably doubled or tripled in the future) at the same time every 5 minutes. I set Xmx50m for every process and our server has only 4gb of RAM, I know that would really slow our server. What I have in mind is to upgrade our RAM. My question is that do I have other options to prevent our server from being slow when running that amount of java processes?

Answer 1

Since you have 50 process and as per your assumption your processes need about 2.5 Gb to run . To prevent your server from being slow you can follow some best practices to set java memory parameters eg set -Xmin and -Xmx the same values and determine a proper values based on your process usage, Also you can profile your process on runtime to ensure that everything is ok.
