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. John W. Colby Colby Consulting www.ColbyConsulting.com
