Mongo currently reports latencies for all operations in milliseconds. However, most of operations on higher-end machines are sub-millisecond. Those operations are just reported as 0ms in the log. At Parse we rely on this log to compare performance of different storage engine. Currently this is really hard since we get useful info only for long tail of operations that take more than 1ms. Would it be possible to report latencies in microseconds? |

Interestingly, on our deployment of MongoDB with RocksDB storage engine, 99.92% of queries are reported as 0ms |
