if anyone else feels like a test
I used this setting for downloading
export CHUNK_DOWNLOAD_BATCH_SIZE=24

---- edit
incase you do not have enough ram for 6gb file download here is smaller test file 1.2Gb archlinux
I just downgraded to last version and am running again to get the actual difference but hell yea this one knocked my socks off. also its nice to see the chunks geting reported as downloaded for the visual feed back.
Yeah, that was actually driven by me when I was trying to download that list of files you sent me, which I’m going to use as part of standard testing from now.
We will have further improvements here soon, like being able to resume downloads, streaming to support downloading larger files, and just generally sprucing up the output with progress bars and such.
now I am slightly confused after downgrading to 0.4.2

its only 5 seconds faster with the latest release but i definatley never saw numbers like this before but last time i tested was around the upgrade time and before that 700k nodes disappeared.
to start with iv got 1gbps fibre and a Mikrotik router
24 is my sweet spot i downloaded the same file multiple times with different values till i found the number with best speed and before the errors start.
I just want to note, that test file is 6GB. However, we do still have the issue with downloading larger files, which is that all files get processed in memory, so you can see an issue if you don’t have enough memory to process those. This will be fixed shortly.
If you don’t have a big connection, use a chunk download size of 1, and the file download command now has a --retries argument. Try using --retries 20. That is the combination I use on my stone-age connection and I can get downloads with either none or very little errors, like one chunk out of hundreds/thousands.
Hmm, that doesn’t necessarily look like any problem with ant. There’s an error message there from Bash. Might be a misconfigured shell. Is the ant binary executable?
Ahh as expected - entirely my own fault trying to be too smart
I had an alias for ant to always include the --max-gas parameter - worked then but seems to fail now.

ant is aliased to `ant() { if [ "$1" = "file" ] && [ "$2" = "upload" ]; then command ant "$@" --max-fee-per-gas 10000000; else command ant "$@"; fi }'
Bear in mind also it is a large file. I noticed 4gb in your hostname, and that file is 6GB. Unfortunately we have not yet converted the downloading mechanism to streaming, so you need lots of memory to download a file that large. Should be coming very soon though.
