Grid Instability

We all know from time to time that the Main Grid becomes unstable with the usual problems of no-rez, inability to TP and terrific lag --- but is there any way LL can fix the basic problems and ensure a half-playable and usable Main Grid before concentrating time and effort on new additions?

I know this sort of thread does pop-up from time to time, but are we now just to suck lemons and put up with the bad performance and treat it as normal?

It's my understanding with the new search features being designed will reduce server load, in return improving Grid stability and performance.

I think that's a step in the right direction, lets just hope it doesn't stop there.
