Re[2]: IFS limitations?

[eric.delong@xxxxxxxxxxxxxxxxx]

     Stefan,
     
     Thank you very much. Seems that finding the right place for answers 
     is more than half the problem. I never did find this information in 
     Bookmanager. 
     
     Thanks again,
     eric.delong@pmsi-services.com

Eric, this is what I've found in the "fine" manual The System 
Administrator's Companion to AS/400 Availability and Recovery Redbook 
(SG24-2161):
     
For practical reasons I guess the question is how You are going to locate 
the files, doing a directory search on a large number of files will 
probably give you response times that have to measured using your calendar.
