[AccessD] Rar vs winzip

I am zipping up some of my big databases in order to get a backup without
the size.  I have always used Winzip but also have RAR installed so I
decided to try both.  I have a quad core on the SQL Server, and it turns out
that Winzip uses a bit of each core but mostly one.  RAR OTOH seems to use
LOTS of all 4 cores, and compresses about 4 times faster than Winzip, I
assume as a result of more efficient usage of the additional processing
power in the additional cores.

OTOH you can winzip and do other things.  RAR tends to suck about 80% of all
4 cores so it is pretty slow doing anything else.  But if you need to zip
something up as quickly as possible then RAR seems to be the one to use.
