Get-DbaAgentJob slowness on applying DatabaseName filter

Verified issue does not already exist?
I have searched and found no existing issue
What error did you receive?
No errors, just lots of time spent waiting for output when we want to return job with Database filter
Steps to Reproduce
Get-DbaAgentJob -SqlInstance sqlserver2014a -Database test_database
Please confirm that you are running the most recent version of dbatools
It takes around 30~40 min of each calling if we choose to apply -Database filter
Other details or mentions
if ($Database) {
$jobs = $jobs | Where-Object { $_.JobSteps | Where-Object DatabaseName -in $Database }
}
this is more like n^2log(n)
wonder if we can use the first jobstep or something to reduce the filter time by a lot

- How many jobs does your instance have?
- What is the average number of steps per job on the instance?
- How many databases does the instance have?
- Do you get the same result in PowerShell or Windows PowerShell (don't use ISE)?
We got like 10 job per db.
A LOT of DBs and on average 4~5 steps per job.
Yeap same result ummm
A LOT of DBs
? Is that under 100, over 500, under 3,000? (Everyone's definition of a lot
isn't the same 😉)
Be aware that if you have a large instance (once you get over ~1k databases) then the performance can play in from your master database on performance. What are the waits showing on the sessions for your scripts?
