It's much faster to just request the specific preference setting

This is an order of magnitude faster than dumping the entire defaults
table.
Of course, that only makes it 300 times slower than 'system attribute
"sysv"', but the point is still valid :)
30 times faster than "read | grep" but still this makes "defaults" 100
times slower than "system attribute".
Cheers, AppleScript: "system attribute" is a matter of 140
microseconds on my prehistoric Pismo.

Don't blame defaults, blame the `do shell script' call.
set n to 1000
set ticks to {}
StartTicks()
repeat n times
system attribute "sysv"
end repeat
set the end of ticks to StopTicks()
StartTicks()
repeat n times
do shell script ""
end repeat
set the end of ticks to StopTicks()
StartTicks()
repeat n times
do shell script "defaults read loginwindow SystemVersionStampAsString"
end repeat
set the end of ticks to StopTicks()
return ticks
--> {7, 739, 2702}
`do shell script' is not an answer for everything :P
