[MacRuby-devel] A QtRuby Version of The GC2 Client has Been Created

[J Silver]

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 ).
