The reason for it is performance reasons. Compression and decompression is happening over and over again without reason. When I unchecked the compression attribute on all the files manually I get lower CPU usage overall. However, every time I restart SC you turn compression attributes on my files back on. Check out the section "When To Use and When Not to Use NTFS Compression" https://www.howtogeek.com/133264/how-to-use-ntfs-compression-and-when-you-might-want-to/ NTFS compression is ideal for:
- Files you rarely access. (If you never access the files, the potential slow-down when accessing them is unnoticeable.) - Computers with fast CPUs and slow hard disks. NTFS compression should not be used for: - Windows system files and other program files. Using NTFS compression here can reduce your computer’s performance and potentially cause other errors. - Servers where the CPU is getting heavy use. On a modern desktop or laptop, the CPU sits in an idle state most of the time, which allows it to decompress the files quickly. If you use NTFS compression on a server with a high CPU load, the server’s CPU load will increase and it will take longer to access files. - Computers with slow CPUs, such as laptops with low-voltage power-saving chips. However, if the laptop has a very slow hard disk, it’s unclear whether compression would help or hurt performance. Also Microsoft has mentioned NTFS compression best practices, You can check out a summary here: https://superuser.com/a/1137127 Date Time Of Last Edit: 2019-07-18 21:55:57
