lz4 is a good option for really high-performance compression as well. (Zstd is my general recommmendation, and both beat the pants off of gzip, but for very high throughput applications lz4 still beats zstd. Both are designs from Yann Collet.)

indeed. though, the recent zstd changes w/ different levels of compression sort of close the gap in perf that lz4 had over zstd. (if interested in this kind of detail for a new streaming storage engiene, i gave a talk last week at the facebook performance summit - https://twitter.com/perfsummit1/status/1337603028677902336)
