Share the results of your SwiftSync IBD on this thread. Important information includes: system memory, network quality, operating system, CPU make, number of peers used.

To test network quality, one may use speedtest-cli, or on MacOS, networkquality -v. Programs like btop also show current download rate. To list CPU information on Linux, run lscpu. For memory, free -h

To allow the program to run detached, use nohup and write the output to a location of your choice. Example (within the node crate):

nohup cargo run --bin ibd --release > result.log &

An example response is shown below.

Hell yeah. Interesting to see a similar time with roughly half the internet download rate.

• CPU: 2.3 GHz 8-Core Intel Core i9 (2 threads per core)
• 32 GB RAM
• MacOS
• Network: 437.464 Mbps (Down) 62.690 Mbps (UP)
• time: 5277 5073 seconds (88 ~84min)

edit: Just saw there is an elapsed time log that most of you are probably using. I had program startup -> no jobs. the elapsed time shows up a couple tens seconds later.

Nice. Seem to be converging around this hour to hour and a half range

Did a test bench on a few devices:
Rpi 5 with 16 GB memory, 4 cores, fast internet - finished in 1h 52m:

time cargo run --bin ibd --release -- --hintfile=../mainnet.hints --tasks=16

which finished in less than 2 hours on mainnet:

Great to see results for a more limited machine. Thanks!

Nice. Looks like it took ~10x longer than the 1gips benchmarks, as expected.

I went a bit overboard with 96 tasks... But it finished in 17.3 minutes:

Boom! Thanks for dedicating your setup to a benchmark!
