A common misconception unfortunately.
The heap is limited to roughly 30 GB, plus a bit of overhead. You will never run in 32bits mode if you set a 32GB heap, because overhead.
From experience, a 30GB heap is similar to a 40GB in usable space. 32 vs 64 bits pointers respectively.
- bogomipz 8y agoSorry what is the common misconception? Exceeding a 32 gig heap size will cause the JVM to stop using compressed pointers? This seems to be widely accepted: https://www.elastic.co/guide/en/elasticsearch/guide/current/heap-sizing.html https://www.elastic.co/guide/en/elasticsearch/guide/current/... I understand there's overhead I wasn't suggesting that all 32 Gigs were useable
