For 10 members, the performance impact is unlikely to be noticable.
For 1,000 members, the performance impact could start to be felt.
A group has to be expanded before email can be delivered. Obviously,
this has some performance impact. However, Exchange has quite efficient
caching mechanisms (some would say too efficient) that ameliorate the
impact of this on active directory.
There are companies (Microsoft themselves comes to mind) where some
distribution lists contain tens-of-thousands of entries. Exchange can
certainly do the job.

Subject: [exchangelist] Difference between Distribution list and
individual IDs

Hi All,


If I do following activities: 


Sending mails to a Distribution list having 10 members?


Sending mail by putting those 10 users in TO/CC list.


I have following question??


Is there any performance enhancement in sending or receiving the mail if
you compare both activities?

Is there any difference in sense of routing the mail to all these users?

Is there any different in GAL Lookup?
