I compaired some timing with poser 6 and poser 7:

startup:  poser7: 61sec,  poser6: 43sec.

loading V4:  poser 7: 31 sec, poser 6: 14 sec.

deleting v4:  poser 7:  13 sec. poser 6: immediately.

I've a system that's similar: a compaq presario, but with celeron-D processor2.8gHz, with 2gig ram and new Nvidia Geforce 6600 GT (which is a gaming-card)
I think this all has to do with the new undo-function, and I think E-frontier has to improve that, but I remember when I by accident deleted a figure and had start all over again.
It's same problem with virus-scanners, they make your system run slower but you can't without them.

-How can you improve things when you don't make mistakes?
