[leveldb] will there be a good perf improvement by avoiding extra get call

[Monu Agrawal]

Hi,
My code needs to behave differently based on if key is present in leveldb.
If key is present, I need to get the value as well.
Since this code is accessing the data using a wrapper library which
provides containsKey method which internally tries to get the value using
get(). So actually my code is calling get method twice if key is present.

I want to know if there will be a measurable perf improvement if I avoid
this extra get call by changing our library's signature (given that the key
will mostly be present in the cache second time).
