The 'proof' shown that aspera is 200x faster shows an ETA of 2:15 compared to 00:09. First of all, this is 15x faster, not 200.
I tried downloading the file using axel -n 32, and it took 1:28, which is only 9x slower. Curious though, when it started out with all threads running it was transferring data at 29594.2KB/s and hit 50% after only a few seconds, but by the end with only a few threads left running it was only doing 5625.8KB/s.
It looks like the performance varies a lot, possibly due to multiple interfaces or wan links being used.. or issues with their server.
Using axel -n 64 over http I was able to fetch it in 50s, which is only 5x slower, and most of that time was spent from 98 to 100% as the last few connections finally finished.
A smarter client that more aggressively re-fetched chunks being downloaded over slow connections would likely match the same performance.
- StavrosK 7y agoYeah, and one window shows speeds in MB/s and the other in Mbps (a 10x difference in units right there).
- justinsaccount 7y agoah, I bet they missed that which is how they ended up with 200x instead of under 20x
- flas9sd 7y agonot to take away from the posts plea. Apart from bit vs bytes, it should be noted the remotes are also on different machines with potentially varying network throughput
