------------------------------------------------
[~eshcar]
With default memstore impl with MSLAB ON and Chunk pool we were able to run
with 32G. But with MSLAB and chunk pool are OFF we need atleast 50G to run with
this load and other GC tunings. Because it generates lot of garbage.
With 32G see if you could run with CompactingMemstore with MSLAB ON and Chunk
pool.
