Description
Issue Type: Performance Issue
Take a big (more than 1500 lines) PowerShell 5.1 script,
Change something,
A PowerShell.exe process will start consuming CPU. It can consume 25% (1 out if 4 cores) for minutes.
I took couple of dumps and traces and everything points to the Microsoft.Windows.PowerShell.ScriptAnalyzer.BuiltinRules.AvoidAlias+d__7.MoveNext() method.
Disabling PSAvoidUsingCmdletAliases rule makes things a bit better. PowerShell.exe starts after saving the script, doing something but calms down much faster.
