I've been watching mongod memory fairly closely (SERVER-20991,
SERVER-20104 etc). With 3.2, memory usage on my non-replica-set deployment is excellent and it is well within expectations for the given wiredTigerCacheSizeGB.
Testing a replica-set with the same workload, the memory appears to push past this limit significantly: using a 4GB argument, actual memory usage is at 6.5 GB fairly quickly after kicking off the run.
I haven't done a full run yet, but will attempt to do so to see if memory keeps climbing or if it levels off.
