RE: Many IFS files in directory

Aaron,

I think this was brought up over at Ignite400.org (you may want to dig
in the mailing list archives there). Large numbers of files do cause
problems when browsing files but as far as serving them goes, it's not
much of a problem until you hit the limit (I don't recall what that it).
The person who was having problems had to deal with really large numbers
of files (I want to say it was over 100,000 -- they were running a site
for the auto salvage industry and had several pictures each of salvaged
cars). We have a directory that got over 50,000 files in it over time (I
believe that WRKLNK didn't have any problems outside of being slow). It
was a real pain to clean up because the Qshell utilities couldn't handle
that many files so I couldn't write a script to do the cleanup. I think
I had to deal with them through either FTP or using one of the programs
from IFSTOOL to do it.

Subject: Many IFS files in directory

I was just thinking today about a project that I am working on that is
cataloging 22,000 PDF invoices (per day) on a Windows machine and the
approach we have taken to ensure top performance is to put no more than
1000
files in each directory by dynamically creating new directories multiple
levels deep instead of putting all files in one directory.

I thought this was just a Windows problem but then a co-worker of mine
said
Linux had the same problem (or similar at least), and that got me
thinking
about all of the files I write out to the IFS with RPG.

Does anybody know if the IFS base file system suffers from the same
dilemma?

Thanks,
Aaron Bartell
