"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."
