Even if it is in a different continent I don't think latency could be the issue with a queue size of 32 packets (for instance, for a connection with 1 second of round trip, with quote_size=>32, the transfer speed would be limited to 1MB/s). Anyway, you can try increasing it to 64 or 128 just to be sure.

Second think to try is changing the transport layer. Use the Net_SSH2 backend or the OpenSSH client instead of plink and see how it goes.
