Re: FTP performance

Based on what the others are talking about, check your NIC settings and your
switch settings. Make sure they match. Full duplex for sure.

   Dmitri,

   I agree with Kirk. Check the line description. If you have a newer
   machine, you probably have a 1 Gigabit card. If so, make sure that your
   connection to the Windows box can support at least 100 MB. That machine
   may also have a gigabit card. If it doesn't, perhaps one could be
   installed.
   Check with the network folks. They may have bottlenecks that they don't
   realize are in place. If they have a policy about this kind of traffic,
   perhaps they can waive it while you are doing your transfers.

     Dimitri,

     Try this as a test. from any windows PC, navigate to
     \qibm\proddata\ca400\express\install . Now Drop and Drop the image
     folder
     on to the desktop. Give it a few seconds to get started and then look
at
     the estimated time to complete. it should be 3 to 5 minutes on a
100Mb
     connection.  I have found in many cases that the NIC in the iSeries
     doesn't setup the connection  very well with the switch it is plugged
in
     to.  Now when this problem is there that time won't be 3 to 5 minutes
it
     will be closer to 100 minutes.  You don't have to finish the
transfer,
     all
     it needs to run for is about 1 minute. To fix this either hardcode
the
     LIND on the iSeries to 100MB and FULL Duplex or do that to the
switch.

     I have also found that wayback in a site's history someone hardcoded
the
     ethernet LIND 10 say 10MB Half Duplex and never fixed it once the
     network
     was upgraded

     Anyway just a thought to check your throughput

     FTP performance

     have to transfer more than a million files from Window server to
AS400
     directory. Copy via Netserver was able to transfer only 100k files in
5
     days, so we stopped it. I think this is FTPs job.

     Is there any difference (from performance point of view) if I will
make
     a
     "GET" using FTP client on AS400 or better to start client on Windows
and
     make "PUT" operation?

     Thanks,

     Dmitri
