Has there been any other updates to the performance issues?
I am running a site which has over 100 matrix rows per entry (with 4 columns per row) and saving times are abysmal (can be over 120 seconds).
I understand P&T is working full tilt on Craft, I just wish there was some love shown to EE Matrix :(

Any help would be welcomed :)
