# RailsMallocTrim

Drop-in library for RAILS app to save some memory.

Gem will call `malloc_trim` after every GC run. This gem solves the problem with the minimum possible effort.

It will check if `malloc_trim` is available and then enables trimming along with loading your Rails app

## Installation

Just put it in your Gemfile:

```ruby

  gem 'rails_malloc_trim', '~> 0.2'

```

Done!

## Impact

  - 99th percentile performance is slightly impacted

  - CPU is very slightly higher

## License

The gem is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT).
