Will Bandwidth Management Improve End User Experience

I have an end user who is 9 times out of 10 on the end of an Internet T1. He uses a Cisco VPN Client to "tunnel" in to the network. Although we (IT) do not see any problems, he often complains of latency on the network, especially opening MS Outlook.  Sometimes it may take 30 seconds or possibly 2 minutes to load.
1) Yes we send and receive voice mail which range in size from 512kb to 10MB.
2)  Most others tunneling in don't have issues.
3)  He sends and receives hundreds of emails a day.

No.  It won't help.

RPPreacher,
What would an alternative solution be if BW Policies wouldn't help?
RPPreacher

User experience is not a metric that one can improve.

Gather statistics from all users; show this user that they are having the same issues that every other user is having.

If they are having a real problem that other users are not having, troubleshoot it.

I would think it possible if not likely that his problem is on the workstation he's using to connect to the VPN, especially if there are other users doing the same thing who don't have this problem.  Either it's under-configured - too little memory, not enough CPU, hard drive issues - or possibly it's contaminated with spyware/adware or loaded up with programs and/or services that use a lot of his bandwidth and steal it away from the VPN connection. Do you have any control over the workstation or laptop he's using to connect?

Hypercat,
Yes we do have control over his laptop. It is or was one of the fastest on the market and still is compared to what the IT Staff or anyone else uses.  He has more RAM (2GB), faster processor (2.4GHz) than anyone else.  Very rarely if ever do I find "crud" on his computer (spyware, viruses, malware etc. etc.).

Could you measure average packet loss & network latency (e.g. using ping) from the laptop towards the servers(s) ? Do this when the laptop is idle and when the users if doing Outlook stuff.

Is it any different from other users ? Can you post the packet loss & latency numbers here ?

robocat,
As soon as I can get the end user to respond to my ongoing request I will do that.
1) End User is connected to an Internet T1 Via Linksys 54G
2) End User then connects to our Network via Cisco VPN Client
3) VPN Concentrator is a 3005 Model.

I don't know what else you will need to know but I will post once I get the data (Holiday ya know...)
Thanks -/SF

Any feedback on latency & packet loss yet ?
ASKER

robocat,
Is this what you are looking for:?
Ping statistics for 192.168.1.163:
    Packets: Sent = 107, Received = 107, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 92ms, Maximum = 280ms, Average = 132ms

I have also run Wire Shark, but not sure what to do with it (just learning).
Your help has saved me hundreds of hours of internet surfing.

An average of 132ms is quite a high latency and may be the cause of slow performance.

Do you use Cached Exchange mode between Outlook en Exchange server?

robocat,
Actually we stopped using Cached Mode with this individual because of a Blackberry Issue. He has two computers and wants to synch both with each computer. He will leave on at his home and come into work and then the synch/reconcile won't work "perfect".  After doing some extensive testing and talking with RIM (Research in Motion) we came to the conclusion that working with two laptops (even though they are the same "account") Cached Mode would not be best.

I (We here in IT) know that Cached Mode offers some great advantages for end user functionality and speed, especially when working over VPN, but we haven't been able to convince the end user of this yet.

So bottom line is we think that the best thing is for 1) him to use ONE computer and just use the other as a spare when absolutely necessary, 2) work in Cached Mode, 3) Do our very best to keep our end (HQ) running at an optimal level.  

This is why I thought that Bandwidth Management would maybe allow for greater speed. Maybe I am looking for a silver bullet solution to alleviate the headache that comes from supporting a demanding Chairman. :-)

One final note on the average of 132ms.  He was working in Europe the other day and it was averaging 200+ ms as an average but we didn't hear any complaints.

robocat,
Now the non-technical solution is needed:

How to convince the powers that be??

Thanks for all of your input!!

P.S. We have Citrix, but the reason we do not use it for Outlook is that we use a Cisco Plugin called Outlook View Mail which allows us to send/receive voice mail through Outlook.  He sends probably 20-50 of these a day and receives just as many. These packets range in size but can be quite large.  Just one more piece of the puzzle we have to sort through.

great follow up and provided answer even if it wasn't what we wanted to "hear" and provided us with verification of what we already suspected.
