I'm having slow issues with photoshop 6. I'm a professional photoshop user since 1993, work on 10-15gb files with 100+ layers. I use a MacPro 2x2.26ghz quad core intel xeon. 32GB Ram. Just did a clean install of lion onto an 500gb SSD hard drive. All my files are SATA connected with a 6TB Raid 0. Nothing except for photoshop, bridge and Capture one is installed on this machine. I experience delays on all fronts. even trying to silhouette a 279mb 2 layer file is painfully slow today.
I've disabled graphics processor
Memory usage is set to 70% (21772mb)
cache levels 4
cache tile size 1024
automatically save recovery information every 10 minutes (how much does this slow the system down?
For ultimate performance, am I better of going back to CS5?
In answer to your subject question, no - it's equal or a bit faster for just about everything I've tested it with.
Have you updated to Photoshop 13.0.1 and Bridge 188.8.131.52 (via Help - Updates)?
Have you tried running it without Bridge (keeping in mind Bridge is set to auto-start under some conditions)?
Does working without »Automatically Save Recovery …« make any difference?
