powershell resource constraints

2008-07-24T21:22:00Z

Hi,
I have a general question regarding the powershell console. Are there
resource constraints? A co-worker of mine says that when he runs an
application, it would use most of the 16gigs of memory the server has. When
he runs the same application on the same server, it is only using 5 gigs of

Thanks Kirk! I am getting the following error message:

'Quest.ActiveRoles.ArsPowerShe llSnapIn.Data.ArsConnection' and try again.

Mmm (local or remote)
file system data parsing?
LogParser.exe -h -i:fs
Input format: FS (FileSystem properties)
Returns properties of files and folders
Perhaps one can even
write the Log Parser query once,
in a plain text file
(that accepts params)
and store this text file
in a network location
that all

Mmm data parsing and at the command line
too (or via COM or .NET "scripting")!
Perhaps use almost any
Windows based product,
but here using PowerShell:
All one long command line (with a
space between most words)!
$list |
LogParser.exe "SELECT
TRIM( EXTRACT_TOKEN( text, 1, '?') )
FROM STDIN " -i:textline -q:on | foreach {

Mmm if one wants to pick the number of lines
to display or to use a data grid to scroll the whole
list in, well just use one's everyday data parser,
Log Parser.
LogParser.exe -h -o:nat
Output format: NAT (Native Format)
Displays output records in the console window
INTO syntax:
<filename> | STDOUT | <empty>

I removed the outer quotes cause otherwise the command is just a string,
PowerShell won't execute it (unless invoked):
PS > $fc = 'cmd /c dir c:\windows /b /s | findstr /r "\.txt$ .\log$" '
PS > $fc
cmd /c dir c:\windows /b /s | findstr /r "\.txt$ .\log$"
PS > measure-command {$fc = dir c:\windows -r -inc *.txt,*.log}

I performed multiple tests (even reversed the commands order) on WinXP and
Vista SP1 with CTP2 (no x64).

For ANY file type you'll have to enable auditing and poll the security event
log. If there's such property for Office files
then the Dsofile.dll com component may help you get it:

This restriction would require explicit mention in the CTP license, so it's
open. FWIW, nothing seems to be spectacularly different in terms of
performance; I have yet to notice anything that has a performance hit
compared to PS1.

2008-07-24T18:22:04Z

Truely amazing, this works. Thanks Kiron. Can you explain how this works?
I have modified to a short script so I can understand. Here is what I think
it does:
$numerical = {
if ($_.name -match '\D+(\d+)\D+') {
[int]($_.name -replace '\D+(\d+)\D+','$1')
}
ls test*.txt | sort $numerical
List out all test*.txt files, pipe to sort which has a script block with a

I found the cause of the slower processing. You unwrapped the pipeline; it's
the difference between this
$fc = 'cmd /c dir c:\windows /b /s | findstr /r "\.txt$ .\log$" '
and this:
$fc = cmd /c dir /s /b c:\windows | findstr /r "\.txt$ \.log$"
The external single-quotes ensure that the piping into findstr is part of

Did you perform multiple tests? With mine, I actually captured the data so
rendering was not involved, and did multiple passes each way since initial
caching seemed to affect performance. On the first pass over the documents
with each method, they took substantially longer.
Also, are you using 32-bit Windows? I used the 64-bit cmd.exe and PowerShell
