MWG 7: Slow downloads from support.canon.de

Hi.

We have an application named ElektroDok (sic!) made by Canon, Germany in place.

This application downloads (on demand) a bunch of PDF from http://support.canon.de/elektrodok/DatenTest.

The files in question are about 100-200KB in size.

What we experience now is that the download of each file takes up to a minute or more.

Using the packet tracing tool and a local Wireshark shows that the download itself goes on in a timely manner.

But after the last ACK was sent by the client, MWG sits there for up to 70 seconds before sending the FIN.

Anyone has seen something similar?

I am not sure who is to blame here. This piece of &%$ß of a software or MWG.

Thanks.

And regards

Peter

Hi Peter!

I have not seen this, but I would like to look at network traces taken on the MWG box that show the connection to the ElektroDok AND to the support.conon.de web server.

Ciao

Sorry!

Next time I will do my homework before posting in a public place. :-(

Looks like we do have an issue with our upstream proxy (hosted by our provider) and/or Canon itself.

If we bypass MWG and use the aforementioned proxy directly, the traces show the same results.

We'll have to investigate in another direction.

Again, sorry.

Regards

Peter
