How fast is seek?

How fast is seek?

I am using the seek function on some large files, for simplicity. Are
there any benchmarks on the speed of this function (WHENCE = 0)?

That varies tremdously with your hardware platform and OS. Why don't
you use Benchmark; on your system and find out for yourself?

As fast as your OS can make it.

Did you mean to ask if there is a faster alternative or something?

In my experience (unix), seek just modifies an internal counter and an
internal flag, and doesn't touch the file at all. So it has next to zero
execution time. If a filehandle is open for write, it may or may not need
to do a flush before the seek, so that may slow down certain seeks.

What's your real question?
