The long journey of making Composer memory-efficient and fast

 PHP’s package manager „Composer” is one of the best of its kind. In recent years, the only point of criticism has largely been the consumption of resources, both memory-wise as well as from a runtime perspective. With version 2 and later minor releases, these areas have received major improvements and we are now left with a very efficient tool that facilitates our everyday work. Join me while I try to recall the past 5 years of trying to make things faster and more efficient and learn about some Composer internals along the way. It will be quite a ride - I promise!
