Benchmark LevelDB implementations in Go using same benchmarking code.
Currently, we benchmark three implementations:
- google/leveldb Official C++ implementation.
- syndtr/goleveldb Go implementation.
- kezhuw/leveldb Go implementation.
In labtop: MacBook Pro (Retina, 15-inch, Mid 2019), 2.3 GHz 8-Core Intel Core i9, 32 GB 2400 MHz DDR4, 1T SSD. There are about 20 GB free memory, 360 GB free SSD, and no swap used in testing.
Default options: No sync, No bloom filter, Snappy compression. The results may not be accurate, and may contain errors. If in doubt, test it youself.
