LDs and such now that peak hours have lots of users

[BennoFlo]

I know live servers only supported a limited amount of users in EQ's classic days.

I've been in a few groups, and I seem to be seeing a lot of LD's during peak hours now that the numbers are getting close to 1100 among my groupmates and myself.

Question for Rogean -
Do we know how well we can scale? Is there a hard limit for number of users? What measures have been taken for this if any?

I'm not complaining, just wondering on the numbers.
