Subj:   Re: Performance issue due to compression?
 
From:   Dave Wellman

Hi,

Technicaly there probably is an overhead compared to the case where both tables are uncompressed, but when you're talking about MVC compression then I doubt if you can measure it.

De-compressing a column compressed with MVC is a lookup of an in-memory array of values, so is trivial.


Cheers,

Dave
