Thanks Josh !
I can see how this would be a problem with GVL. I was able to get it
acceptable by limiting log size to 20 messages instead of sending entire
log mandatorily. Small change allowed the server not to choke the client
as much. Only reason I read every 1 byte is to try to allow n-sized
multi-line messages. Not sure how I would add message sizes to the
protocol, though it could be in like a LENGTH message, then sending the
longer one and using #read to get the size of the buffer. I think that
you're right in saying that can speed it up to 100% of the MacRuby and
RubyMotion speed ( fast ).

you're reading in a byte at a time. That, combined with the GVL, can
seriously slow things down. You can either increase the number of
bytes you're reading each loop or, ideally, use TCPSocket#read with a
buffer. It's a bit more work to get right, but it should resolve your
performance issues.

Want to report success using QtRuby library with the qtbindings gem.
Internally, Able to use Signals and Slots through the advanced
techniques described around the web.
Now have a working version of the chat available in the GlobalChat2
repository.
https://github.com/jsilverMDX/GlobalChat2/tree/master/gc2-qtruby
It runs on 1.8.7 and 1.9.3. It lacks many of the features of the
advanced MacRuby client coming soon to App Store.
It uses QtDesigner for the GUI files with the UI loader and should run
natively on Mac, Windows and Linux.
However, one thing. The MacRuby client is DAYS faster getting a big log
back from the server than QtRuby, and the signal is obviously not to
blame. This happens on both 1.9 and 1.8.7. Any ideas?
HAPPY TURKY DAY!
