But that still doesn't save away, "oh, it's only slow because the filesystem is so slow". Assuming that's true, that's a very integral part of the system that can't readily be swapped out by most people. You can't say "the system is actually really fast, it's just the OS that's slow", because the end result is just plain "the system is slow." |

If performance is so critical, people do find ways around this. Just to give an arbitrary example since you mention file systems:
Oracle implemented their own filesystem (ASM Cluster File System (ACFS)):
> https://en.wikipedia.org/w/index.php?title=Oracle_Cloud_File...
"ACFS provides direct I/O for Oracle database I/O workloads. ACFS implements indirect I/O however for general purpose files that typically perform small I/O for better response time."
