Re: Socket Speed Question - RPG vs PC

Did you check their frame size also?

Don, (and others interested in these changes)

I went to do a test on a system that I know has a bigger pipe than I do out
in the country using DSL (hopefully not AT&T DLS either...)

I checked and their system was set to 8192. Probably from the old days as
I've been a consultant for them for over 20 years.

I did a test and got .51mps speeds. Horrible!

I changed it to 65535 and got 4.46mps.

I changed it to 8388608 and got 26.21mps.

Still not as fast as I'd like to see... but better. It is a pretty busy
local county government so I'm sure their pipe is always in constant use as
well.

Hi Brad,

So you changed the TCP attributes (chgtcpa) send and receive buffer

sizes

from 65535 to 8192 and you saw the improved performance ?

Is that correct ?

Thanks

Don

Well, that certainly made a difference! went from 8mbp to 23mbps. I
even
went back and forth to keep testing. Very cool! Those were HTTP tests,
so
then I tried HTTPS and got 21mps (remember, my line is only 30mbps...

out

of town DSL is all we really have available).

I think it would be better if my kids weren't "distance learning" and
using
zoom all the time too.

Thanks, Patrick!!!

Hello Brad,

The main problem is the speed vs my pc. 30mbs speeds on my pc

(which

matches my poor internet speed haha!), 8mps on my application and even
slower on FTP client on the IBM i.

It appears to me that your performance problems are related to high
latency connections. This can be partly solved by using large send-

and

receive buffers.

I'd recommend to set them to max (8 MB) in IBM i and try again.

If this is not solving your problem, it gets interesting. ;-)
