This kind of delay is often a result of the process trying to
access some remote filesystem. Or, maybe you have DNS problems
on the server.

That size is not overly surprising. The size of the lastlog file
depends on the highest uid used to login into the system. In your case
you seem have pretty large uids. Every uid slot in lastlog takes
276 bytes. So you had login attempts from a user with a uid 1615639.
