I want to make a script that can copy or move a file (10MB) by php. But I dont know how long does it take to do that. Anyone can tell me about this.

Depends from where to where.
But it will be almost like on your computer, a matter of seconds. 2, maybe 3, it depends how the server is I/O busy, and your process priority.

But it should not be a problem for a 10 Mo file.

I think It's just like from /home/storage --> /home/temp_dir

And how is about 100MB file?

Again, it all depends of the server.

I was more referring about the type of support (Net shared directories, ftp, ssh, tape drive, cd/dvd) than the path.

Is it a shared hosting server or a dedicated server?
Does it use Fiber channel, scsi, sata, ata, gigabit lan, 100 M Lan?

How much ram is free, how much cache is free, what other programs are running in background ?
What CPU load does it have?
What running load does it have. Is it swapping ?
Does your account have process limitations ?

These will all have an impact.

You have only 1 thing to do, try it.
Time your transfers, if you have ssh access, monitor activity (with "top") and see if it's ok.

You won't find anybody except your sysadmin giving you timing on your server operations.
But really, 100 Mo, that's a bit large for a casual web operation.

Like Tripy said though it should only take a couple of seconds. Unless your server is lacking resources.
