Get-DbaAgentJob slowness on applying DatabaseName filter

[xshen1]

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

What PowerShell host was used when producing this error

Windows PowerShell ISE (powershell_ise.exe)

30-40 minutes?!?!

• 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)?

[xshen1]

We got like 10 job per db. A LOT of DBs and on average 4~5 steps per job. Yeap same result ummm

[wsmelton]

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?

Maybe a -FirstJobStepDatabaseName would go better on Find-DbaAgentJob. It is already a bit confusing on what parameters are supported on Get-DbaAgentJob versus Find-DbaAgentjob.

I saw about a 30% improvement on my 132 job server with about two steps per job which has only 6 dbs including system. Went from 13 seconds to about 8 seconds

Get-DbaAgentJob mysqli | ? { $_.jobsteps[0].databasename -eq 'master' }
