### Compiler (GHC) Versions
For best performance use GHC 8.10 or 8.8 along with `fusion-plugin`
(see below). Benchmarks show that GHC 8.8 has significantly better
performance than GHC 8.6 in many cases.
GHC 8.6 and above are recommended. For best performance use GHC 8.8 or
8.10 along with `fusion-plugin` (see below). Benchmarks show that GHC
8.8 has significantly better performance than GHC 8.6 in many cases.
Please do not use GHC 9.0 for sensitive applications, initial
evaluations have shown severe perf regressions with GHC 9.0.
GHC versions 8.6 onwards are fully supported along with `fusion-plugin`.
`fusion-plugin` is not supported for GHC versions below 8.6.
GHC versions 8.0 onwards are supported without `fusion-plugin`. However, note
that some packages we depend on (e.g. `network`) may support only last three
major versions of GHC.
GHC 8.2.2 may hog memory and hang when building certain applications using
streamly (particularly the benchmark programs in the streamly package).
Therefore, we recommend avoiding using the GHC version 8.2.x.
GHC 9.0 has some performance issues, please see [this issue]
(https://github.com/composewell/streamly/issues/1061) for details.
However, upcoming minor version updates may fix some of these issues.
