Well, wait, you were talking about two different things. You noted
that, during the cvs2svn conversion, you saw a long delay at a
certain point:

I responded to this, saying it might be a single large file being
committed at that point, and I still think that's a likely answer.
Not sure if many minutes is a reasonable time for a commit of a 38MB
file to take... suppose I could try it. But since that's only an
issue at the time where you add such a large file to the repository,
I'm hoping it's not something you'll run into every day, and so the
fact that it takes some time should not be a hindrance to you.
The other issue you talked about is that, at the end of a checkout,
it waits for a long time:

I don't think that's related to the cvs2svn conversion issue; I don't
think it has anything to do with how many files you're getting or how
big they are. Indeed, I have no idea what causes it; we see this
phenomenon often (but not always) on our company's Subversion
repository, and it's driving my coworkers nuts. Actually I'm not sure
if it's exactly the same as what you're seeing, because we see it
mostly when committing, after the file data has been sent, but before
it returns control to the prompt. And we also see it when updating a
working copy, after all the data has been received but again before
regaining command control. But I don't know what to do about it,
which is why I didn't respond to that part of your question.
