PowerShell Get Event log and using the message argument and SLOW speed

Question

The problem with get eventlog is it is god awful slow.
Everyone wants you to pipe the results to a where statement which makes it 100x slower expressly when there is already a –message argument there.
Problem is I am having little luck. Still taking 30 minutes or more and not producing any results even when looking for a computer I know is there
Can you confirm the syntax is correct for this? If it is correct how do I make this usable?
Thanks
$before = (Get-Date).AddMinutes(-30)
$after = (get-date).AddMonths(-1)

$after

I am working with google and the help file.  Need to learn it better did not even know about -par 
if i type (see below)
If replace the word User or Computer with the actual name i need to find i get a big fat error that says I am  to stupid.  
Get-WinEvent -ComputerName MSDCSERV02 -FilterHashTable @{Logname='Security';Data="Computer"
# Or
Get-WinEvent -ComputerName MSDCSERV02 -FilterHashTable @{Logname='Security';Data="User"
# Both work
