What is the average time (may be in millisecond) of Linux file operations?

Hi,

What is the average time (may be in millisecond) of Linux file operations? For example, usually a process accesses (e.g., reads, opens, writes, or mixing of those operations) a file, how long by average of the accessing time that a process has operated with a file, in general?


Can anyone point out some reading about this? I really appreciate this.


Best,

Winai

This question is more hardware specific. An SSD is faster then a HDD. An i5 at 2.5 Ghz is faster then at 1.7 Ghz. The North/South bridges affect this also. Ram amount, load of the system. Size of the file.. Really hard to say.

Yes, it's very hardware dependent and it also depends on the file system in use of course (e.g. ext2/3/4, btrfs, reiser4, etc).
