LZ4

One of the data compression algorithms that provides minimal processing latency, creating a CPU load 3-5 times lower than GZIP, and virtually no performance degradation even on weak processors. It is the only one of the algorithms under consideration with instant decompression and is therefore recommended by default for 90% of workloads. It is ideal for transactional databases (e.g. PostgreSQL OLTP), Redis caches and virtual machines with high disk activity.
