I decided to install the 16th Ubuntu as it is called next to Windows 10. Before that, I compressed the volume to 50 GB and actually allocated 8 GB for the swap partition in Ubuntu OS. But now I have very slowly loaded Windows itself, after a reboot. If you previously started in seconds 4-5, now it can reach in a minute. And yes not so long, but everything is learned by comparison as they say. I wanted to make a defragmentation, but it seems like she is already automatically scattering resources. Tell me how can I correct the work of the systems?

    Most likely the problem is that after compression, there is not enough space left on the Windows boot volume. This is a feature of the NTFS file system - if the volume of free space of a volume is less than 12% of its full volume, this leads to fragmentation of the MFT, which catastrophically affects the performance of the disk subsystem.

    I recommend to increase the boot volume so that at least a quarter of it is free, and defragment the service files of the file system (MFT, etc.) - and the regular defragmenter does not know how to do this, use third-party software. And always make sure that there is enough free space on this (as, indeed, on the other) volume.

    • The fact is that I allocated memory from the hard disk. And the disk that has more to compress with Windows is simply nowhere else, it initially divided 1TB equally - one for system C and another for hard. Accordingly, 200+ GB are walking there (which is in C, that in D). But the drive that I separately allocated for ubuntu is already busy at 70%. Perhaps it should be increased? - Morozov
