# klauspost/compress

> A collection of optimized pure-Go compression algorithm implementations: zstd, S2, deflate, snappy, lzw, huff0, FSE, plus gzhttp HTTP wrappers and parallel pgzip. Packages are drop-in replacements for Go's standard gzip, zip, zlib and snappy.

## Useful for

- Swap compress/gzip for flate to speed up compression without code changes
- Enable zstd in an HTTP service via gzhttp for request and response compression
- Use pgzip for parallel gzip compression of large files

## Why it’s here

- Star-counter measurements on 2026-10-27 (UTC), 11:42–13:41: 5702 → 5703 stars (+1). This is the change over that interval.
- Estimated end-of-day forecast: about +2 stars, using observed gains and the previous day.
- GitHub Trending Go today: #20, +3 stars.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
