Make Your Performance Work Count: The 20% Rule Basically, the idea behind the 20% rule is that the end users are "blind" to changes that within the limit of 20%. If you have a regression issue that is lower than 20% you might want to think if business wise you want to improve it.
Here is a great sentence from his post:
"If it is fast and ugly, they will use it and curse you;
if it is slow, they will not use it."
