I have uninstalled PGP WDE but if anyone else has it installed they can chip in. By the way, these are with FileVault which makes very little as far as I can tell.
Here is the copy of a 2GB file :
$ ls -al Windows-s001.vmdk
-rw-r--r--@ 1 root root 2146762752 Mar 14 14:42 Windows-s001.vmdk
$ time cp Windows-s001.vmdk test
real 0m51.242s
user 0m0.007s
sys 0m4.385s
$ sync; time cp Windows-s001.vmdk test
real 0m49.169s
user 0m0.007s
sys 0m3.708s
$ sync; time (cp Windows-s001.vmdk test; sync)
real 0m47.942s
user 0m0.007s
sys 0m3.742s
If anyone has PGP WDE with an SSD, can they give it a try?
