I'm going to post this again since with every release this never gets fixed. So a few have mentioned since 6.7.0 download speeds have slowed (to cache). My dockers will download (to a ssd cache) at 100-110 megabytes a second when its normal. Since 6.7 and now 6.8 RC1 my downloads are 50-60 megabytes a second. When i reset a network setting or reboot the server my first download will be back to normal (sometimes throttle mid download) and the second download will be back to 50-60.
I've tested by running the program on another computer and works fine, I've installed it on a VM on the same unraid server and it works fine. Its only the dockers that get this speed issue.
