Title Body

I need to walk through a folder with approximately ten thousand files. My old vbscript is very slow in handling this. Since I've started using Ruby and Python since then, I made a benchmark between the three scripting languages to see which would be the best fit for this job. The results of the tests below on a subset of 4500 files on a shared network are Python: 106 seconds Ruby: 5 seconds Vbscript: 124 seconds That Vbscript would be slowest was no surprise but I can't explain the difference between Ruby and Python. Is my test for Python not optimal? Is there a faster way to do this in Python? The test for thumbs.db is just for the test, in reality there are more tests to do. I needed something that checks every file on the path and doesn't produce too much output to not disturb the timing. The results are a bit different each run but not by much. #python2.7.0 import os def recurse(path): for (path, dirs, files) in os.walk(path): for file in files: if file.lower() == "thumbs.db": print (path+'/'+file) if __name__ == '__main__': import timeit path = '//server/share/folder/' print(timeit.timeit('recurse("'+path+'")', setup="from __main__ import recurse", number=1)) 'vbscript5.7 set oFso = CreateObject("Scripting.FileSystemObject") const path = "\\server\share\folder" start = Timer myLCfilename="thumbs.db" sub recurse(folder) for each file in folder.Files if lCase(file.name) = myLCfilename then wscript.echo file end if next for each subfolder in folder.SubFolders call Recurse(subfolder) next end Sub set folder = oFso.getFolder(path) recurse(folder) wscript.echo Timer-start #ruby1.9.3 require 'benchmark' def recursive(path, bench) bench.report(path) do Dir["#{path}/**/**"].each{|file| puts file if File.basename(file).downcase == "thumbs.db
