Subject Re: (ZipDirectory) RE: storing index in third party database.
Date Wed, 03 Apr 2002 19:27:22 GMT
I am doing some testing on managing the underlying data in a zip archive and
found that there is about a 15ms hit to use a zip vs. grabbing directly from
file system.

This is very reasonable for me vs. having to manage moving around a 1000's +
files.
