    There is one thing that bugged me about OSX. To copy files is SLOW.

    Let me explain.

    I stick in a USB stick and copy 40 presentations, each 20 megs or bigger. On a PC at work running Windows 7 with a slower processor, it takes 15 seconds.

    At home on a Mac pro with dual processors and 32 gigs of ram, it takes 60 seconds.

    This is ALWAYS the case. No matter what computer, the windows side seems to be faster. I own 8 macs at home, and I am not slamming on macs. Its just seems that IO (ssd or regular) is SLOW.

    Does Mountain Lion address this issue?

    (btw even if I format the drive to the mac os extended its still as slow)

    I have the same problem, but this is nothing, try to create encrypted DMG file, I used to be able to copy at 20 to 30mb/s to encrypted DMG image before, now its dropping to below 1mb/sec :( its freaking horrible, wish I never upgraded and paid apple money because each upgrade its actually worse than before from performacne perspective. I have 32GB RAM, i7 iMac and just drives me nuts the drop in performance :(

    I've experienced something similar, copying media files. Maybe it's the OS's IO or the file system. Windows does handle these operations better.

    I found that using the terminal command cp to be a bit faster so I don't think its the IO subsystem

    Are you folks copying to a FAT32 formatted USB key/drive by any chance? That will be much slower than copying to an HFS+ (Mac format) drive.
