If you are using bulkloader you might want to tune some flags from:

http://code.google.com/appengine/docs/python/tools/uploadingdata.html#Command_Line_Arguments

The particular ones that might interest you are:

--num_threads
--batch_size
--bandwidth_limit
--rps_limit
--http_limit

Running with the defaults will probably lead to really slow uploads
especially with very small entities that can be batched 1000 at a time. That
would give you a 100x speedup right off the bat.
