I'm trying to find folders created by a propritary data aquisition software with the .aps ending--yes, I have never encountered folder with a suffix before (some files also end in .aps) and sort them by date. I need the whole path
ls -dt "$dataDir"*".aps" does exactly what I want except for the recursion. find "$dataDir" -type d -name '*.aps' does everyting but is excruciatingly slow on windows remote shares. It takes about 45 seconds to find 27 folders. 8 are one subdirectory below $dataDir and one is 2 subdirectories lower. There are a few hundred files and each .aps folder has 7 subfolders with a bunch of files (many called setup.aps which seems to be slowing the find). I know I can get use the printf inside find to get a date column and sort and cut it but it would be even slower.
ls -dt does everything I want except the recursion. the -R option in ls is a completely different animal and does not do the kind of recursion I'm looking for. -1R is sometimes useful but in the above command it does nothing.
You are kinda stuck. The handling of your request lives on the other side. The problem is - what happens on the windows side? Changing commands on UNIX is not going to help much.
I am assuming you are using CIFS/samba, try: Faster Samba (SMB / CIFS) Share Performance - Eggplant Systems and Design
I'm working under Cygwin64 in a all-Windows corporate environment. (This utility runs side by side with the data aquisition software allowing users to edit run names, comments, validate/invalidate/exclude data. The propritary software is so user unfriendly and clunky (I guess that's what the thousands of dollars is for 
). I happen to have special privilages on the share drive I am using for development but won't for the deployed system.
ls is plenty fast but I can't do the recursion. Not sure what other commands are out there. On the plus side, I have some really fast hardware to run on

part of it is windows file sharing. It takes about 0.6 seconds vs 45 seconds on my local machine. However, find itself is dozens of times slower than ls.

I'm living with find find "$dataDir" -type d -name '*.aps' -printf '%T@|%p\n' | sort -nr | cut -d"|" -f 2 ("|"being an windows disallowed path character) until one of the forum Awk or Perl deities pops in It is taking no longer than the find itself (~45 seconds).
