I'm hoping you can help me unwind an annoying performance issue I've uncovered in Windows 7; one that doesn't seem to be documented at all if the Google is to be believed.
I recently upgraded my laptop (a Lenovo T60p, C2D T7200 proc, 2GB RAM, ATI X1400) with both a new SSD (an OCZ Vertex 60 GB) and Windows 7 Pro x64. Performance and stability has been terrific. Especially that sub-30-second boot time!
Initially, I had desktop composition disabled, so that Windows 7 was running without the Desktop Windows Manager. I just recently enabled it when I discovered that it's pretty damn sexy, and had little impact on battery life (if anything, it seems to have gotten better).
However, now my laptop takes much longer to boot - about an additional 30 seconds or so following the Windows login screen. When I disable DWM, it goes back to booting quickly. Now I realize you can't get something for nothing, but 30 seconds for a single process? A fairly lightweight process that you can enable instantly in the desktop environment? My hunch is that that just isn't right - something is interacting badly. Thus my questions are:
1. Does anyone know if this is normal behavior for DWM?
2. Is there anything I can do to address this?
3. Or, is there a good forum/online resource where I could post this (rather esoteric) question?
