Stream: IG creation
Topic: host resources

First of all, I'm a noob with this stuff and just a server guy - but when running an IG publish - there seems to be quite a bit of RAM and CPU usage. We have a 4 core CPU and 32Gigs of memory on this server (shared). Whenever someone publishes and IG, these resources get used up pretty good and if someone sneezes, the server gets pinned down (maxed cpu/ram). We have been throwing more RAM and CPU at this VM for months now. Does anyone have any recommendations on RAM and CPU for this java task? or even how to manage this with Java options or ....?

32 GB should be fine if running a single IG. The IG process itself doesn't generally go much over 16 GB (it can operate in less, but may thrash with certain IGs).

16gb for a single IG seems pretty excessive...

Take a look at UTG :)

The IG publisher is a single threaded java app. It should not max use on a multi-core machine. (with one single exception where it launches a background thread that lasts about 4-5secs). OTOH it uses plenty of RAM, yes. It always reports how much java thinks it is using
