Running the latest nightly from SD card but I did have this problem before on the last stable version. I have media stored on an SSD, I want to copy some of it to a USB3 memory stick. Both media are plugged into the rear USB3 ports. The SSD is NTFS, USB stick FAT32.
This is what I did. Using file manager, I selected a directory to copy which contains 3 sub directories, each of which contains 26 video files of varying sizes up to 500MB. I start the copy to the USB stick and it whizzes along nicely at first but slows dramatically and stays slow after a short while. I have tended to give up and reboot when it gets to around 400KB/s. If I decide to transfer files on an individual basis, each file copies quickly but there seems to be a slowing after several have been done although not to the snail’s pace of the directory based approach. Interestingly, this slowdown seems to go away if there’s a short pause before selecting the next file.
I’ve tried to be as accurate in my description as I can be and to define the situation so it can be recreated. My question is can something be done about it in the new kernel or is it something that’s a Kodi limitation?
