Subject: Re: ftp slow

You might try locating the part that is slowest.

#!/usr/bin/ruby

require 'net/ftp'

ftp = Net::FTP.new('E0152')

puts Time.now
st = ftp.login("opecon", "123",0)
puts Time.now
files = ftp.chdir('/home/opecon')
puts Time.now
ftp.gettextfile('DAILYC', 'DAILYC')
puts Time.now
ftp.gettextfile('DAILY', 'DAILY')
puts Time.now
ftp.close

and take timings at the same point in the perl code and see where the 
problem lies.

Does ruby take longer to logon?
Does ruby take longer to CD?
Does ruby take longer to transfer a file?

I also note that perl is just getting the files and ruby is getting a 
text file, maybe there is an overhead in ruby hangling a transfer as a 
text file (line ending conversion etc) that perl is not having to deal 
with. Can't you just use ftp.getbinaryfile() and see if that speeds 
things up. It will at least tell you where the problem might be.
