# Compression Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

MinIO server allows streaming compression to ensure efficient disk space usage.
Compression happens inflight, i.e objects are compressed before being written to disk(s).
MinIO uses [`klauspost/compress/s2`](https://github.com/klauspost/compress/tree/master/s2)
streaming compression due to its stability and performance.

   recover from another I/O failure.
 * Fix problems where spdy/3.1 headers may not have been compressed properly.
 * Fix problems with spdy/3.1 and http/2 where the wrong window size was being
   used.
 * Fix 1.5.0 regression where conditional cache responses could corrupt the
   connection pool.

This includes work such as compiling, testing and documenting software, plus sharing that software via publishing and dependency management.
This platform is agnostic to what kind of software is being developed.
It might be Java or Kotlin libraries running on the JVM, Gradle plugins, Android or iOS applications, C++ libraries, and so on.

This platform does not provide special support for a particular language or ecosystem.

  // Run Enums.getIfPresent on that other TestEnum and then return a WeakReference containing the

  // (and therefore its ClassLoader) from being unloaded, then this WeakReference will never be
  // cleared.

settings allow for more staggered delay in terms of usage calculation. The scanner adapts to the system speed and completely pauses when the system is under load. It is possible to adjust the speed of the scanner and thereby the latency of updates being reflected. The delays between each operation of the scanner can be adjusted by the `mc admin config set alias/ delay=15.0`. By default the value is `10.0`. This means the scanner will sleep *10x* the time each operation takes.

In most setups...
