Basically what I am saying by that is that there is at least 4 seconds page render time difference.
It's pretty bad, really bad for me.
This is an excellent plugin, hopefully there will be some improvements done.

Entries Per Page 10 (def 20)
Refresh Rate 60 (def 30)
Time Between Status Updates 15 (def 5)
