Most effecient way to download torrents

Hi everyone, I'm a bit new here, well, a lot new here really, so sorry if this question has been asked before.

I was wondering, if I wanted to download ten torrents, what would be the quickest and most efficient way to download them? Should I start downloading them all at once, at the same time, or should I download them one at a time, and wait until they each finished before starting the next one?

Generally, I use Azureus, and download files in batches of three, and then when they're complete, leave three seeding at a time. That way, if the tracker goes down on one torrent while I'm not there, the others download and upload, so I'm not wasting my time. Would that be the most efficient way?

Just wondering if my logic is right there or not.

depends on your max download speed.

3 or less downloads @ the same time would be the best thing todo.

If the tracker goes down most of the time you can continue downloading.
