Thanks. Found this file:


and changed

    def rbuf_fill
      timeout(@read_timeout) {
        #changed by cburt
        @rbuf << @io.sysread(1024)
      }
    end

to

    def rbuf_fill
      timeout(@read_timeout) {
        #changed by cburt
        @rbuf << @io.sysread(16384)
      }
    end

Now downloading a 150MB file takes 25 seconds compared to 21 seconds for 
straight curl and 40-sum seconds for curl using a popen.

The problem now is that I have a web API client that I was going to 
package into a ruby-gem that would have been easy to install. Now I have 
to tell people to start hacking the standard library if they want to use 
it. Uhhg!
