AirDC++ 4.10

Postby maksis » 08 Jan 2021, 17:46

Version 4.10 includes various performance and reliability improvements.

Improved transfers speeds

Version 4.10 allows the operating system to optimize socket buffer sizes, which multiplies per-connect speeds in many cases. Especially transfer speeds between users that have long physical distance between them will be increased.

Note that you will generally not see any speed improvements with people using previous versions of AirDC++.

More reliable extensions

Extensions are now less likely to exit due to a timeout when the system is under heavy load. If you still see timeouts, you may increase the socket ping timeout from the Web UI (Settings -> System -> Advanced server settings).

Changelog

API and Web UI changes

- https://airdcpp-web.github.io/2021/01/0 ... .11.0.html

Changed:

- Let the operating system set the optimal socket write/read buffer sizes by default (can multiply per-connection transfer speeds with faster connections, https://bugs.launchpad.net/dcplusplus/+bug/1909853)
- Improve hashing speed by increasing the read buffer from 256 kilobytes to 1024 kilobytes (https://bugs.launchpad.net/dcplusplus/+ ... comments/9)
- Increase the default file write buffer from 64 kilobytes to 256 kilobytes

Fixed:

- Fix inconsistencies with filelist transfer logging
