Start-Job is now 6-10x slower, and does not preserve $env:PSModulePath #7402
Description
Steps to reproduce
$iter = 10
$env:PSModulePath = 'Custom PSModulePath'
Measure-Command {
for( $i = 0; $i -lt $iter; $i++ )
{
$job = start-job -ScriptBlock { Write-Host $env:PSModulePath }
}
}Expected behavior
I should be able to kick off ten jobs in just a few seconds (maybe 2 or 3). When the results of the job come in, I should see Custom PSModulePath. This is the behavior in 5.1.
Actual behavior
It takes between 12 and 20 seconds. That's longer than a second per job! (and I'm not waiting for the job to finish; this is just the time for Start-Job to return) And then the output is the default module path.
