TsavoriteKV - UpsertAsync

[orcohennn]

There isn't an UpsertAsync method for TsavoriteKV as in FASTER. Is there a way to do it asynchronously?
Inserting even a small amount of data takes too much time. Is there a way to improve performance?

Upsert does not directly hit storage so there is no reason for it to be async. I am surprised you are seeing perf limits. A small stand-alone repro would be great. We can upsert at millions of ops/sec. cc @TedHartMS
