I'm suffering from longer project loading times too...in fact project saving times as well. 

I've had loads of problem with this upgrade. Some important Vst's and Vsti's could no longer be found by Sonar no matter how many times I reset or reinstall the vst's/vsti's. a good example: cannot find Trillian in Sonar although the DLL file is still in my vst folder. My work around is to use Omnispere to load my bass patches. If I did not have omnisphere, This wouldn't have been funny. I have done a roll back and followed the intructions to a T just in case I missed anything. I have even uninstalled sonar removed every cakewalk related software from my system and registery and reinstalled everything with no joy. I have had to revert to using dim pro 32bits in my 64bit rig due to dim pro 64 constantly crashing sonar, and I am also noticing that my computer is strugling and crackling a lot with only a few Vst's and Vsti's loaded. The fact that many of us windows 7 users seem to be experiencing more problems now makes me also wonder if optimizing Sonar for Windows 8 has created some problems for us. My rig: Processor AMD Phenom(tm)IIX6 1055T Ram 8GB Win 7 64 bit

X2a installed fine.  Stable as a rock, no issues.
 
X2 been stable since quick fix.

Definitely slower load times!!

Thats pretty strange. Have you tried resetting your audio configuration to defaults? 
I suggest that you call  support since can help you troubleshoot it. Its likely to be a configuration issue. 

Thanks for the suggestion Noel,
 
I set my X2a preferences the same as X1 wherever possible. Among the equivalent settings, the only differences were in Dithering and Panning Law. After doing so, playback of the problem project had no more X2a audio glitches and the space bar stopped play back on a dime. Out of curiosity, I tried to recreate the problem by setting the preferences back to their failing state but X2a no longer glitched with the old settings making me suspect the simple act of saving the preferences cleaned something up. No worries now, I'm happy with X2a.

...but X2a no longer glitched with the old settings making me suspect the simple act of saving the preferences cleaned something up.

 
I think that's a good possibility. I've seen similar results in other software as well, where the act of simply resaving the prefs/ini file can make a difference.
 

100 plug-ins in one project?

I'm just chiming in to keep track (no pun intended!). I haven't noticed anything odd other than it's not crashing as much and the now time works better and I can record midi in a loop w/o missing a bunch of stuff :P I admit though, I pretty much abandoned all hope after X2 and have mostly just been working in live and studio one. Host ho, yes I AM!

How is the .ini file being resaved here?  Just going to preferences, then config file, then hitting "apply"?  Or was a slight change made?
