No need to turn it off unless you have specific concerns about performance or resource usage.

For a long time I turned off Superfetch, now called Sysmain, thinking it caused more problems than help. But I discovered that memory compression in Windows 10 is linked to the Sysmain service. Should I still disable it or keep it on now?
Superfetch enhances performance by prioritizing cached programs in RAM. For general users, default settings work well, and altering memory configurations isn’t necessary unless you want to test.
In reality, the process behaves differently than expected. For instance, in games like World of Warcraft, I noticed more random frame drops when Superfetch was active compared to when it was turned off, even though the game ran on an SSD. Turning Superfetch off made a clear improvement, which is why I now disable it on all my computers.
