Subject Re: Blob in another directory
Date Fri, 01 Jun 2007 14:03:11 GMT
Hi Stefan,

At this time, I am only doing some tests for big repositories and one of 
the requisites is distributed workspaces. I need to store data in 
different hard drives, if I use internal blob's, it works.
I still not sure which is better: internal or external blob ;-)
