Speed

We stared using EPDM on May 2009. We now have a project subfolder with over 1,000 subfolders. When we open this project folder with over 1,000 subfolders in it, it takes over 10 to 15 sec to brouse into this folder. What can we do to speed things up or is it that we are still on EPDM 2009, SP 3.0 on SP4.0 has fixed this on maybe even EPDM 2010 will?SolidworksSolidworks Pdm enterprise Pdm
