Łukasz Mierzwa 5597020a60 Use github.com/klauspost/compress for gzip and zlib ... klauspost/compress is a high quality drop-in replacement for common Go compression libraries. Since Prometheus sends out a lot of HTTP requests that often return compressed output having improved compression libraries helps to save cpu & memory resources. On a test Prometheus server I was able to see cpu reduction from 31 to 30 cores.
