This is an example benchmark with various workloads (90% read / 10% write, etc) on a collection of 1 million elements with different goroutine pools. In this example we're combining two types of transactions:
- Read transactions that update a random element (point-read).
- Write transactions that update a random element (point-write).
Note that the goal of this benchmark is to validate concurrency, not throughput this represents the current "best" case scenario when the updates are random and do less likely to incur contention. Reads, however quite often would hit the same chunks as only the index itself is randomized.
Below are some results from running on my 8-core machine (Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz).
