normal d9beb7690f net/protocol: optimize large read case ... There are several places where rbuf_consume is called with @rbuf.size as its length arg; simplify that case by avoiding the slow String#slice! operation in favor of a lightweight replacement. The following script exhibits reduced memory usage and runtimes using the time(1) command: 2.9s => 2.6s 70MB => 12 MB --------- require 'net/http' require 'digest/md5' Thread.abort_on_exception = true s = TCPServer.new('127.0.0.1', 0) len = 1024 * 1024 * 1024 th = Thread.new do c = s.accept c.readpartial(16384) c.write("HTTP/1.0 200 OK\r\nContent-Length: #{len}\r\n\r\n") IO.copy_stream('/dev/zero', c, len) c.close end addr = s.addr Net::HTTP.start(addr[3], addr[1]) do |http| http.request_get('/') do |res| dig = Digest::MD5.new res.read_body { |buf| dig.update(buf) # String#clear is important to reduce malloc overhead, # but most Ruby programmers don't do this :< buf.clear } puts dig.hexdigest end end ---------- * lib/net/protocol (rbuf_consume): optimize for @rbuf.size == len [Feature #14268] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61602 b2dd03c8-39d4-4d8f-98ff-823fe69b080e		2018-01-05 02:22:23 +00:00
