At the end of the Switch (or merge) process, Subclipse has to
"Refresh" your Eclipse project. Even a project much bigger than yours
this should be very fast. When it is not fast, that is usually a sign
that you have a significant number of files that are out of synch with
Eclipse. For example, if you do Ant/Maven builds in the same folders,
and Eclipse does not know about all of the modified files. What then
happens is Eclipse recognizing all of these changed files slows things
down as it fires events through the system letting all plugins know
about them.

To confirm, this, the next time you need to do a Switch try this:

1) Right-click on your Eclipse project and take the Refresh option.
2) Then do the Switch option.

Since the project should already be refreshed the Refresh that we do
should run faster.

Now, one other thing you do not mention is how many files come down as
part of the Switch. Because another thing that is going to happen is
all of these changed files are going to kick off the Eclipse builders
etc. to compile the files and report warnings etc.
