2. If you are running hosted engine, make sure you have enough
entropy, the
login page generates a couple of tokens using secure random,
which
eats away
at your entropy budget heavily and since hosted engine is a VM
it is
possible
that you don't have enough entropy. You can check your entropy
level
with
this:
cat /proc/sys/kernel/random/entropy_avail

159 is horrible to be honest, that is most likely the cause of your
problems. Anything below around 300 is bad.

Alex,
I checked that on my engines, and the entropy is around 120.
But those are NOT hosted.
Can you confirm this lack of entropy enduces no slowness on dedicated
engines?

Lack of entropy is what causes super slow login. I creates some tokens on
login that use up entropy. However once you have logged in it re-uses the
token and the entropy should not be an issue after that for the most part.
He didn't actually say but I suspect that after the initial minutes wait for
the login, it was not THAT bad after that. Not like what we are seeing with
your system.
