Not really: the transfer rates are passed from the neon library (in case
for http transfers). And neon is the DAV library with not connection to
local disks. So it would be highly unlikely that the transfer rates did
not indicate real network transfer.

Make sure your network monitor is working correctly.

But even if somehow this would be wrong as you suggested: you'd have to
report this on the svn mailing list since that data is passed from the
svn library to the clients - TSVN only shows the data it gets.

Best guess for that failure: your apr library on the server is not
compiled with large file support.
