I have created a simple test (just to download a file from famous site like flickr or google.) I run the test locally (either from jmeter directly or talk to the locally running jmeter-server,) the average time is 250ms and the throughput 29.4/s. Then I remote start this test on a host (which has much better internet connection,) the resulting average time is 225ms but the throughput is extremely low — like 2/s or even below 1/s. The average time number looks reasonable. The throughput number is totally useless. It appears that the jmeter is somehow counting the time between the local jmeter driver and the jmeter server, rather than just averaging the throughput a experienced by every jmeter servers. How can we get the right throughput numbers in remote/distributed tests?

figured out. The reason is that when you have multiple remote jmeter servers configured, but start only one, jmeter is not smart enough to know that! so it keeps waiting for other non-starters to reply, causing the stats to plummet. The work around is to ensure all jmeter server started and working,
