The gdb remote protocol is a simple request/response system with
default-small packets.  Throughput is severely limited by round-trip
latency.  Some gdb parameters are available to increase the packet
sizes, but nothing to affect latencies.

	set remote memory-write-packet-size NUMBER
	set download-write-size NUMBER

However, these only help if the stub on the other side can accept
bigger packets.  Otherwise, you are out of luck.
