How to reduce the memory consumption of an HTTP:Server?

Help & Support
1

Hi everyone,

I’m trying to understand why an HTTP::Server consumes at least 400mb of memory.

Here is an example of an HTTP server that consumes 411mb of memory just by being started.

I would like to know if there is any way to reduce memory consumption because I have a project that starts several servers on the same server and this will cost me many gigabytes of memory.

Example:

require "http/server"

server = HTTP::Server.new do |context|
  context.response.content_type = "text/plain"
  context.response.print "Hello, World!"
end

address = "0.0.0.0"
port = 8080
puts "Listening on http://#{address}:#{port}"
server.bind_tcp(address, port)
server.listen

Memory usage:

Thanks.

I think this is the memory consumption of the compiler plus the executable, you could use crystal build and run the resulting binary instead

That was it!

Thanks, I’m not used to working with compiled languages.

Solved, just use crystal build
