Re: FTP from IFS using zip file update

[DrFranken <midrange@xxxxxxxxxxxx>]

 The log on process to IBM i is not the quickest thing on the track. In 
addition there are nearly always exit programs attached to FTP so you 
are experiencing the extra steps needed to get logged on.

I would investigate the need to 'quit' and log back on for each file. If 
you can do that you'll probably see the thing finish in just a couple 
minutes.

You can simulate this with a visual example by creating a script in a 
notepad document that does 'open i.p.addr.here' then 'user pass' then 
'put somefile' then 'quit' and repeat that 10 times with 10 little 
files. Now cut and paste that into FTP on your PC.  Now change the the 
script to only have 'open' at the top and only have 'quit' on the 
bottom. You will see a dramatic difference.
