** 2024-08-24 when DL more than 1 URL, one thread is combining blocks, other thread can continue DL.

-w,--worker INT          concurrent HTTP download worker (default: 5)

it's already supported.

- the speed issue is server side block size is too small. (2MiB block)

  should use bigger block when connection bandwidth is high as 200Mbps.

  HTTP has initial connection cost.

  it's not using HTTP/2.

  Either make the block size bigger or use HTTP/2 server + HTTP/2 client.

- add a option to set block size.

** 2024-08-24 rd-api add an option to set block size.

--block-size 2M,4M,8M

- there is no packet loss from agem10 to de06 via ipv6.

  rd-api is not needed to transfer big files.

- 

when network is unstable, but bandwidth/throughput is good, use a larger block

size can improve DL speed.

** 2024-08-24 build rd-api, rd for aarch64 and distributed it on pypi.

- currently the python pkg is marked works for all arch, which is not correct.

live compress easily. If the client request compress as param such as

?compress=zstd. default is no compress.

- when the source file is just tar, not compressed format like squashfs or

  zip, this can speed up transfer by delaying compress.

- when the source file is tar/qcow2/raw, not compressed format like

  squashfs/zip/mkv/mp4, this can speed up transfer by doing real time compress

  at transfer time.

** 2024-03-12 rd, add an DL remaining time estimate, based on estimated DL speed.

each block has a block size. I know when it is started and when it is

yes. see Route Patterns.

** 2022-03-15 rd client, is there a built-in repeat/loop function?
