Solr devs, I've seen some warnings on the Solr Wiki about staying under a 32G heap to take advantage of compressed pointers. Has anybody that has gone over the 32GB soft limit (but still under 64GB) played with increasing the byte alignment? For example -XX:ObjectAlignmentInBytes=16
I'm wondering if anybody has seen this make an impact on their heap sizes and/or GC tuning. There have been several issues about Lucene correctly estimating RAM usage, but that's not really what I'm after. Thanks, Mike
