Change performance impact tooltip to percentage (only take 2 decimals after the dot) rounded up

For example, current value:
<img width="539" src="https://api.zenhub.com/attachedFiles/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBBMmQzQnc9PSIsImV4cCI6bnVsbCwicHVyIjoiYmxvYl9pZCJ9fQ==--0b1ef999164ed328601f9c333605b34dd23ef5d4/image.png" alt="image.png" />

Expected value:
`2%`
