Framework is very expensive and consumes heavily Apex CPU time.
Inserted @3500 Accounts and updated using batch apex ,

Account has NO workflows, processbuilder, flows or validation rules, matching or merge duplicate rules.

The Account handler has empty override methods
public void beforeUpdate(){}
public void afterUpdate(){}
