Here are some benchmark results on OSX 10.10.5 with 2,7 GHz Intel Core i5, SSD, Mutable (with compensating actions) model, fixed 1GB heap size, ParallelOldGC collector and CpuConsumption.HIGH set.
|VM Buffer IO||MMAP IO|
|Mean latency, micros||57||87|
|Worst latency, mls||2.446||9.36|
|Worst percent (>3mls), %||0||0.0021|
With immutable model this tests showed a little worse performance, but not so much. With mutable model without compensating actions latency mark suffers a lot.
Please note, that despite this numbers, IO Mode should be selected carefully according to your durability expectations. Read more in special article about it.
