After publishing post statistics on that post was ok. Everything was tracked and inserted in database.
After editing that same post slimstat just forgot to track it and statistics for that particular edited post does not appears anywhere.
Forget it, i just tried to do same thing on my test environment and stats in working ok.
Ups, typo, my SlimStat version is 3.5.9.
I disabled CDN and UAN (Settings -> Advanced tab) and my site site response is fast again.
