logon times when whole school logs in. Any Advice?

[ranj]

Hi

 

I read on here before but couldnt find the appropraite forum. We use roaming profiles in our school and over time our main file server is struggling to cope with demand when all IT rooms login.

 

I read on here that maybe moving roaming profiles onto another server may help with this. I was wondering if anyone has tried it and if it has made any difference.

 

Much appreciated

It depends on the size of the roaming profiles. How big are they?

Pupils have a maximum limit of 30mb, whilst staff do not have a restriction. thanks

Ok, I'd look at pruning some of those staff profiles first.

Also depends on the number of users and quality of the network infrastructure. Is it absolutely crucial to use roaming profiles?

Was about to say you'd be best without user changeable roaming profiles, if only for the kids. We have mandatory profiles for everyone which are approx 2mb and we've still had problems in the past. Realy couldnt imagine 30mb per user flying about,

 

30mb * 300 users (for example) = 9gb

 

Thats 9gb the server has to read and send. Even powerful servers would have a problem doing that all at once in a reasonable amount of time.

 

Rough calculation -- byte = 10bits ... 90Gbit of data on 1Gbit/s NIC

 

90 / 1 = 90 seconds.

 

Thats 90seconds without taking disk reads or any other factor into account, like bandwidth to workstations. And then the client has to process the data so...

Also if you have powerful DCs you can share the load between them by having %logonserver% in the path to the profile.

we had this problem from 5-15 mins. moving the profiles from one server to another made a big difference back to 2ish mins max 5 on a bad day

 

i also made sure i excluded as many paths from the profiles Application data folder as possible using GPO.. i didn't redirect that cause it has issues with ie proxy settings..

 

i assume that you redirect my docs and desktop so they aren't in the roaming profile...
