"I am currently looking at the performance of our index_read, since it was in
the past pinpointed at the source of problems.
While the read side is the one that is mostly interesting, I would like to test
both - besides anything else, it is easier to test reads after writes so we
don't have to create synthetic data with outside tools.
This patch introduces the write side benchmark (read side will hopefully come
tomorrow). While the write side is, as mentioned, not the most interesting
part, I did see some standing from the flamegraph that allowed me to optimize
one particular function, yielding a 8.6 % improvement."
