Great news. Could you give a quick summary of how you did it? Do you know if it was a leak I introduced (in Vty) that was causing most of the slowness, or were all the leaks important? Perhaps you could give some tips for Yi developers who want to be sure they aren't creating bugs in the future. Is just "-hc" cost-center stack profiling enough? --~--~---------~--~----~------------~-------~--~----~ Yi development mailing list yi-devel@googlegroups.com http://groups.google.com/group/yi-devel -~----------~----~----~----~------~----~------~--~---
