I'm playing around with a host of tweaks on the stock VZW ROM. This link here
http://forum.xda-developers.com/show...9&postcount=86 contains my current settings. I'm leaning towards a bigger filter cache and smaller disk cache (the difference between the two being what sort of read-ahead and write cache is being performed). Once I've got some more hours under various configurations I'll post them. But this will make quite an improvement in the responsiveness of the device. The biggest problem with the VZW device is the gimped RAM and the bloated HTC dialer (WTF - why does the dialer require 10M???) - but it is much nicer than the stock WM dialer IMHO, and it supports/recognizes the VZW CDMA ##xxxx programming codes where the stock dialer does not. Less RAM leaves less room for bigger caches. Verizon just makes me scratch my head sometimes - but that's a different thread.
