The first time a user logs in their MyWorkspace is created, so if
these are new users that could be the reason for a spike in load. Also
if you have course management integration when a login takes place the
site memberships for a users courses are refreshed which again can be
an expensive operation.

Could you describe the problem a little more and your setup.
Did the load return to normal after the logins had completed?
Were may other users on the system at the same time?
What were they doing after logging in?
