Hi,

Thanks a lot for ITS#8324! For embedded, not server, use case that change adds much convenience.

I have tested the master from .NET via P/Invoke and do not see any major slowdown with default options. To insert 10M <int32,int32> pairs inside a single transaction v.0.9.14 takes minimum 3400 msec, latest master takes minimum 3750 msec. This is not scientific, just best result from 10 runs. Sometimes both timings increase to 5000+ msecs. On average slowdown is visible but tolerable - from 2.9 Mops to 2.6 Mops (absolute numbers are still awesome!). With Append and NoSync I could get 3.45 Mops on the same test with master build.

However, with WriteMap performance of master drops 3x to 10000 msec or just 1 Mops, while for the v.0.9.14 performance with WriteMap improves to 2350 msec or 4.25 Mops.

Is this the cost of convenience or it could be fixed so that WriteMap still "is faster and uses fewer mallocs" as the docs say?

Best regards,

Victor
