Stephen We just had to laugh - "Literally, we have seen directories (accounts) with upwards of 4,000 files & dictionaries!"
We have around 100 000 files (incl dicts)... We just have to ask now, in light of our recent conversations regarding triggers, file performance, and JFS2, do your statements still hold that JFS2 for 32-bit UniVerse 10.1.2 would be the ideal way to go considering we're running standard AIX5.2 with no additional (to AIX) indexing at shell directory level? Would the number of files in the directory affect trigger perfromance? Would installation of "Reiser" type systems improve our system be of any use? Would JFS2 cope with that number of files per directory? -----Original Message----- From: Stephen O'Neal [mailto:[EMAIL PROTECTED] Sent: Thursday, 30 September, 2004 5:39 PM To: [EMAIL PROTECTED] Subject: Re: [U2] [UV] Max Files Per Directory [EMAIL PROTECTED] wrote: > I've heard some discussions in the past regarding limiting the number > of files per directory to help OPEN performance.

Our experience shows that it effects the length of time it takes to open a file. The reason is the length of time it takes to traverse the directory table to find the file. Literally, we have seen directories (accounts) with upwards of 4,000 files & dictionaries! We saw improvement in speed when reduced to the 1,000 entry range. But this is pail in comparison to keeping files opened thru labeled common. We HIGHLY recommend holding files open in common! FYI, Steve Stephen M.
