Speed (or lack of) issues

[biaya]

Hi
We have recently set up users on our server so that they can dial into our Citrix server, One of these users is sharing an internet connection through a 56K analog modem and has no ability for leaseline or broadband. Because of this they are, as you can imagine, extremely slow. Somebody has suggested us plugging in one of our ISDN30 lines into the Citrix server for incoming access - will this speed them up and how would i even start on this one?

Thanks a lot for any help/advice you can give.

The analogue modem won't talk to the ISDN.....

How slow is slow...???!! Citrix Client should only be using approx 14k bandwidth, it's never going to be as fast as LAN but it should be usable....how have you got the incoming connection between the Citrix Server and the dial-up set-up...???

Slow is very slow. A 15 minute log entry took them over an hour! I'm not sure what you mean about the incoming connection to the dial-up, but I'll try to tell you how we are set up. We have our main server, with Citrix attached to it, and each user has Citrix Client. I use this at home through an internet connection on a 56K modem and it isn't, to be honest, that slow. Yet these guys are horrendously slow. They are now considering satellite broadband - what do you think?

I was meaning about how your network connections are set-up...do you have a RAS Server that handles the incoming calls from your modem users...??? How is that then interconnected to your Citrix Server...??? Are they connected to the same Switch/Hub..?? Does the RAS Server also handle DHCP addressing for the clients...??? Are the addresses/sub-net/DNS/WINS addresses that it passes to the clients OK...??? All these can potentially have an impact on the response times...

Okay, I'm a bit dumb on this bit - I don't know the answers to your questions, other than other users dial in and they don't have an issue (myself included) with speed. So I think it is to do with the set up their end rather than ours. Do you agree?

OK, if everyone is dialling into the same RAS server (do you all use the same phone number..??) then it probably isn't an issue with the networking....you still need to determine how the DHCP is working (it's this that is probably setting up the IP Addressing on the clients), it could give everyone the same basic set-up or it could be configured to give addresses based on login name....???

Are the "slow" users always slow...??? Is it just one application that they use...??? Does the application appear to be OK if a "local" user performs the same task...?? How does the "log entry" application work...??? Who set-up their client..??!!!

Sorry for the questions...

Anything is probably going to be faster than the dialup connection, but there's probably an answer to why the connection is appearing to be so slow for this particular application....the Citrix Client is probably one of the fastest dial-in connections that you can use, it is optimised to only pass screen updates between the client and server which is why it only uses a 14k bandwidth, as long as the application is not expecting to read large ammounts of data from the client device is should be OK...????

I tend to agree with the earlier speculation that the issue lies at the "problem users'" end, since everybody else seems to be happy with the speed of the connection.

I think Highland might be on the right track - is the user in question attempting to transfer large files up or down the connection?

It could be that this is something to do with the way the "logging" app works - a local file may be updated then transferred to a network location.

Hope this is in some way helpful CitrixEngineer@yahoo.co.uk
