Terminal Server Performance

[Guest OS360_ITMAN]

Good Day to all

 

I have a terminal server running 180 connections currently, of these 150 are

low end connections only using a web application and with them on the system

is humming at a mere 10% CPU usage, but once I load my other 30 power users

with Email, and office then the usage rises to 70% CPU Usage.

 

Most of the CPU usage is used by Outlook as they have PST which are 2GB's

and more.

 

The worst response on the power user session is with Email very slow at times.

 

I am considering installing Exchange as currently we use POP mailboxes from

our ISP.

 

Will this alleviate some CPU resources or will it be the same.

 

In essence is Exchange mail better performing than POP Mail in a terminal

server environment.

 

Thanking you in advance.

RE: Terminal Server Performance

 

Absolutely. The RPC connections to Exchange Server hosted mailboxes has much

less overhead than the constant local reads and writes to a PST. PST are

even worse when located on a file share.

 

I would recommend that you install Exchange then use EXmerge or the Outlook

client to import user's PST into the Exchange Information Store. If you have

network storage space, disable PST so all user's mail is stored in the

Exchange Information Store.

 

 

Changing from POP to SMTP will also save your Internet Bandwidth, as emails

to mailtiple recipients at your company will be delivered to the exchange

server as one email, and only downloaded and stored once, as opposed to each

user downloading their own copy like they do with POP.
