On  my side, removing the "Reader.*" pages programmatically, and removing
all related entries in activitystream_events table, solved my issue. Home
page now shows up normally, and displays correct events in activity stream
:)
I think the Reader was generated too much entries too fast.
Thanks for help, anyway I'll give a try to the Admin tools for further
perfs improvements,

  Well you would need to delete the unnecessary data.
It's a bit complicated
 to explain because it really depends which one is showing up as wrong

  You probably should script deleting the feed documents. Otherwise you'll
  only remove part of it.
 You might have added data to additional tables and missing indexes show
 the
 problem.
 Using the Admin.Tools indexes in addition to the default ones my help.

 Hi, I am Yang Li, and one small question: I tried the database 
 sanitycheck
  script and found there are some rows selected,
which is not desirable. 
 What
  I'm supposed to do?
