Re: Why is the iSeries so slow

Ken,

I seem to recall others on the list reporting this specific problem in the 
past.  The problem was with the DUPLEX setting on their Ethernet *LIND. 
The problem was that the setting was causing the iSeries to constantly 
renegotiate with the switch it was connected to.

If you have it set to *FULL, try changing it to *AUTO (which is what the 
message I remember said did it for them).  If you are already *AUTO, then 
perhaps try setting it to *FULL.  You should also confirm that the 
LINESPEED and LINKSPEED are set to 100M (assuming that is the speed of 
your network.

Here is the message from the archives I am referring to:

I am obviously assuming here that you are direct connected to a switch. If 
this doesn't help, I would also check how much memory you have assigned to 
the pool that the FTP server jobs run in.

My current calculations result in a 4gig file taking 15 hours to FTP from
the iSeries to the PC client's hard drive. Is this for real? Are there any
tweaks to make this process more reasonable?

This the most simplest file transfer I can think of. It's an ASCII file
created with the CPYTOSTMF file and is housed in the /home folder of the
IFS. Once switched to namefmt 1, the GET command simply retrieves the 
file.
No translation, authenticated user and plenty of memory, CPU and disk
space. So what am I missing or is the iSeries really not capable of
handling one of the most basic tasks any simple PC based FTP server can
achieve?
