Dear All,

Can anybody whether ISA server is CPU intensive or not ?
If I am using Core 2 duo CPU now and update to Core 2 Quad, will the ISA performance improve ?  i.e. client will feel internet response faster !


How about changing the windows server from 32 bit to 64 bit ? Will that help ?


Thank you for your help.



Thanks

If you move to quad, you have to pay for four licenses.

HTH,

IS Server Can not be installed on a 64 bit Machine.

Only its Firewall client can be installed on 64 bit machine.

HTH,

How big is your network?
ISA will run even on a PIII server and you will not really notice any speed improvements on small networks.

Depends on what you are using ISA for. Certain features like SSL bridging, NLB, application-layer filtering will all impact CPU usage to varying degrees.

It may be worth checking out the following doc:

http://www.microsoft.com/technet/isa/2006/perf_bp.mspx

I always find it is better to scale horizonatally (e.g. add more servers) as this provides a lot more benefits than having one "uber-ISA".

I was under the impression that MS licensed on physical processors e,g, if you have dual or quad core CPUs these still count as one physical?

e.g. 1 dual/multi core CPU = 1 lic
2 dual/multi coire CPUs = 2 lic

This is based upon the following: http://download.microsoft.com/download/f/1/e/f1ecd771-cf97-4d98-9a1b-b86e3f24e08f/multicore_hyperthread_brief.doc

Cheers

JJ
