Diego,of which is the IBM i. We have both DNS addresses specified on our TCP
I am uncertain how best to answer.
DNS is not running on our IBM i.
"Is your DNS configured correctly?"
->Can you be more specific? We have 2 DNS Servers on our network neither
iNav and HTTP Admin), I was wondering if there wasn't a configuration issue
"How fast is your DNS?"
->Not sure how to determine this.
"Have you tried disabling DNS?"
-> No, DNS is not running on the IBM i
"Have you tried to increase buffer size to 1 MB?"
-> I have not, I suppose I could give this a shot. Currently at 65536.

Paul,
Is your DNS configured correctly?
How fast is your DNS?
Have you tried disabling DNS?
Have you tried to increase buffer size to 1 MB?

Well, I know that using CHGTCPA to change these:
TCP receive buffer size . . . . 65536
TCP send buffer size . . . . . . 65536
REALLY helped FTP. Significantly. Enormously. Like WOW!

Thanks Brad,
I, too, thought that netserver might be the issue.
Since we also have sluggish response with HTTP interfaces as well (with
(disclaimer: I am not a network person. )to newer faster hardware).

I think it has something to do with netserver... I've had this problem
since
V5R4 and it's still there on V7R3. Better, but not great (more likely due
than one, it seems to go quicker.
Sometimes I can right click on a file and open it (with something like
notepad++), other times it takes a few seconds before the open with
notepad++prompt
appears.
When deleting one file, it seems to take forever, but when deleting more
giving a dialogue to save the file... but "save" seems to be instantaneous.
When editing an IFS file, "save as" seems to take 10 seconds or so before
just put up with it for now... I hope to hear an answer as well.
I hope these are along the same lines as the problem you're having.. I've

I seem to have a very bad performance issue between the IBM I and my--
network when working with files in the IFS and applications on my PC.
We are on IBM I V7R2.
I have an excel .xml file called mytest3.xml (literally, that is the
file name). The file is 17k and has about a dozen rows and columns.
When I open the excel file from the IFS the file takes about a minute
to load (using MS Excel).
When I take the IFS file and move it to the network, the file opens
instantaneously. (Note that moving the file from the IFS to the
network using File Explorer is instantaneous).
.I have often thought that network, and also HTTP interactions, with
our IBM I have been slow, but have never been able to pin it down.
The Excel experiment above seems to highlight the issue.
The question is, what approach can I take to try address this issue?
How can I investigate the problem?
Any help appreciated.
