I know there was already another thread on this, but I didn’t completely understand. I would love to re-read it but I accidentally deleted the emails. I remember something about changing a buffer size. Can anyone please send me that thread or basically tell me what the fix was, because I could desperately use it. Also, I’m not 100% sure this fix would apply to my situation, but basically I’m going out to a website and retrieving the HTML. Is that fix applicable here and would it improve speed? Thanks for your help. Thank You, Ben J. E: removed\_email\_address@domain.invalid ---

The fix is basically to go into your $RUBY\_HOME/lib/ruby/1.8/net/protocol.rb, find the method called rbuf\_fill and change the sysread to something bigger than 1024. Probably 8192 or 16384 would be good enough for your purposes. – Ola B.

Ruby being Ruby, you can also just reopen the class and redefine the method in question to your liking: class ::Net::BufferedIO def rbuf\_fill timeout(@read\_timeout) { @rbuf \<\< @io.sysread(8192) } end end But it’s probably not a good idea to release code like this in a library to the public.
