Kiwi

# Benchmarks

Following are the benchmarks comparing Kiwi with BuntDB on a MacBook Pro (8th gen Intel i5 2.4GHz processor, 8GB RAM).

Following are the key differences due to which Kiwi is a little slow:

  1. BuntDB supports transactions, i.e., it locks the database once to apply all the operations (and this is what is tested).
  2. Kiwi supports dynamic data-types, which means, allocation on heap at runtime (interface{}) whereas BuntDB is statically typed.

The above two differences are what makes Kiwi unique and suitable to use on many occasions. Due to the aforementioned reasons, Kiwi can support typed values and not everything is just another "string".

There are places where we could improve more. Some performance issues also lie in the implementation of values. For example, when updating a string, not returning the updated string avoids an extra allocation.
