exFAT File-System Performance On Linux 5.9

When looking at the startup time test profile with various I/O workloads happening in the background, the exFAT file-system with the Linux 5.9 kernel driver is roughly on-par with the performance found by EXT4 and F2FS. The exFAT kernel driver here performs substantially better than the FUSE driver, to little surprise.

The random read performance measured by FIO did come up short for exFAT on Linux with even the FUSE implementation performing better.

With the random write performance the kernel driver allowed much better performance than the FUSE driver but was still behind the Flash-Friendly File-System and EXT4.
