Description

Enhancement Type

Improve an existing feature

Describe the enhancement

MeowIce provides 2 versions of the flags - one using the standard G1GC and the other using ZGC.

ZGC is a latency focused garbage collector which may have some benefits for higher end CPUs in reducing stutters due to garbage collection.

Contributor guide

Research direction
Review the current MeowIce flag implementation for G1GC, then replicate the pattern to add a ZGC variant. Ensure to check the startup script and environment variable handling.
