Payslips, dogfooding and text fluidity

Never heard paystubs in UK, I had to check a couple of dictionaries to understand it was an Americanism for payslips.
Dogfooding is an order of magnitude more common without space.
The other two proposed changes are to make the reading more fluid.
OLTP, not OLAP

In the context, it makes more sense OLTP, not OLAP
Fix typos in Ch03 plus Whatcha doin'

Proposed improvements for Ch03

perfomance -> performance
interal -> internal
Chpaters -> Chapters
Adding missing -s
await and the Async suffix -> await unary operators and the Async affixes (as there are both suffixes and infixes, and "unary operators" 
clarifies that affix doesn't refer to "await")
"and then send it back up to your web" -> "and then sends it back to your web" (I found "back up" confusing, even in the context)

"organization defined. From password expiration every 3 months that take down systems that hasn't been updated to deleting "inactive" user accounts that take down systems to" -> "organizations defined. From password expiration every 3 months that takes down systems whose configurations haven't been updated to deleting "inactive" user accounts that takes down systems to" (I think the proposed update, with the explicit reference to configurations, is more clear)
