For the performance testing, we need:

• Get the statistics to measure the correct ops/sec as Matthew Saltz before.
• Change LinkBench to use the new oplog format by setting a server parameter.
• Get the numbers from existing 1-node replset and 3-node replset tests in a patch build.
• Update one workload to include 100,000 small updates in a transaction and test its performance with the old and new format.
• If the performance drops, run LinkBench locally with gperftools enabled to get the profiling to pinpoint the slowdown.
