Subject: lotus notes bandwidth /slowness

Feedback Type: Problem

Product Area: Notes Client

Technical Area: Administration

Platform: Windows

Release: 8.5.1

Reproducible: Always

I'd like to share some frustration and find out if other people see this as well, besides that Lotus Notes is fat slow client and we all know this, and has its own issues which people who needs to support this product trying to explain end users and management that it is learning curve rather then Notes problem, there are things that you cannot explain to other and still tell them it's normal and how it suppose to be. To the point, we are 8.5.1 domino 8.5.1 Notes clinet most mobile users workking remotly.
Problem we are facing is that although we have 4x full T1s dedicated for Notes traffic we are experiancing unaceptable slowness, after engaging our ISP to tell us why our 4 T1s showing only 0.3 Mbps upload when testing from internal network we were given spreadsheet with external IPs connecting to our mail server on notes ports which are eating up all the bandwidth, as you can guess after comparing those public IPs connecting to our Domino mail server with external Notes client IPs we found in Domino Admin console there is nothing suspecious, those were all our Notes clinet, users trying to work... question is how it is possible that 43-40 Notes clinets can beat up 6 Mbps pipe so badly that it is unusable?!
we open PMR with IBM to see why single Notes client is taking so much bandwidth and if there are any tweeks to minimize it, besides getting a lecture about notes client architecture and that we cannot comapre anything else with it no help.
It is sad to share this info but becasue of that, no only becasue of that but because this is what pushed decision over the edge, by the end year we are migrating to exchange 2010 and outlook 2010.
Does anyone is facing same problem when external notes client are eating all you bandwidth to the point where it is unusable?
also as a side note this is regardless if external client is using local replica or mail on server, as long Notes is open and there is connection to server it is still doing it. If it is put in Island mode bandwidth is released.
