Three weeks ago I posted that, although we had no estimated time yet for the release of the Testlive patch, it would be safe to assume it would take two to three weeks for it to be released live. During that time we have been hard at work trying to address the server stability issues that have been occurring lately, which was the reason why pushing the Testlive patch was put on hold in favor of addressing this. That is why we have to specify that we do not have a date set in stone, as this kind of problems can arise at any moment.
Performance issues will come in a later patch than Testlive. The first step towards that is the “death lag” fix we released yesterday. If it was an issue that we could fix “instantly”, we would. Rest assured of that
