Did you consider using somthing else that can zip strings in the memory, like http://www.sweetpotatosoftware.com/SPSBlog/PermaLink,guid,a85aaf3b-7e8f-478f-b06c-c115f610caae.aspx ?

>I have a utility that zips thousands of memo field data. I am using Dynazip, but it requires it to first write the memo field to a table, then zip it to a zip file, and finally read the zip file to a string to save back to the memo field. The process takes forever. I think if I create a RAM drive for the temporary file it would greatly improve the speed.
