I accidentally stumbled upon this issue:
Copying a 119 MB zip file took 4 times longer in Terminal (cp) than in Finder!
I copied a file of 119 MB size in Terminal with
time cp file.zip file2.zip and it took about 20 seconds.
As this seemed quite slow to me, I went to the Finder, selected the same file and hit
Cmd-D (duplicate) and it took less than 5 seconds to create the copy, that is only 25% of the time it took with cp!
Is there an explanation for it - might this be systematic?
- MacBook 13" white (2007)
- OS X 10.6.8
- Internal hard disk WDC WD10JPVT-00A1YT0
it really seems to be a cache issue: I tried the opposite order with another file and copied it first in Finder and then in Terminal, and in this case also the second copying was much faster.
