You hit two bird with one stone. This explains why I sometimes get a slower
HotSync process. My Windows 98 laptop is used for HotSync and it only has
32 megabytes of RAM, which gives you a rough idea of the need for
efficiency. It wasn't long ago that I disabled synchronisation of all
applications apart from a few that I actively use.

This appears to offer an unsafe solution that is troublesome over the long
run. I suggest that the OP learns to tolerate the slow HotSync or give up
one of the synchronisation nodes (desktops). Multiple desktops are better
off avoided where possible, also when it comes to general filesystem
management. Bookmarks, domains, E-mail and so forth likewise.
