Hmmm another thought. Linux also (typically and traditionally) does a lot more library reuse thanks to the open source ecosystem. So, there's less DLL hell and fragmentation there. That could be another reason for my not noticing.
Most of my system libraries that any random app needs are already loaded and ready for use after boot.
Yeah - you might be onto something there - I suspect fragmentation matters a lot for the spinning disks. If you've got huge disks in there, you probably have mostly sequential reads for just about everything.
