in thread MS Word over Win32::OLE "suddenly" extremely slow

Here is a short example that displays the problem on the new computer

#!perl use strict; use warnings; use Win32::OLE; use Win32::OLE::Const; use Cwd; print "Load Const\n"; my $wdc = Win32::OLE::Const->Load("Microsoft Word") || die "Unable to load constants ", Win32::OLE->LastError(); print "Load Word Engine\n"; my $Word = Win32::OLE->new('Word.Application', 'Quit') || die "Unable to start Word Engine ", Win32::OLE->LastError(); $Word->{'Visible'} = 0 ; $Word->{'DisplayAlerts'} = 0; ## Open template print "Add new doc\n"; my $doc = $Word->Documents->Add() || die"Unable to open new doc ", Win32::OLE->LastError(); # Turnoff background operations $Word->Options->{'Pagination'} = 0; $Word->Options->{'PrintBackground'} = 1; $Word->Options->{'BackgroundSave'} = 0; my $range = $doc->Content; $range->Collapse( {Direction => $wdc->{wdCollapseEnd} } ); my $max_row = 25; my $max_col = 7; print "Creating table $max_row x $max_col\n"; my $t1 = $doc->Tables->Add($range, $max_row, $max_col); my $start = time; print "Start Data Entry\n"; foreach my $row (1 .. $max_row) { foreach my $col (1 .. $max_col) { $t1->Cell($row, $col)->Range->{Text} = "$row-$col"; } } print "Finished Data Entry ", time - $start, " secs\n"; $start = time; print "Start Center\n"; foreach my $row (2 .. $max_row) { foreach my $col (1,3,5.. $max_col) { $t1->Cell( $row, $col )->Range->ParagraphFormat->{'Alignment'} + = $wdc->{'wdAlignParagraphCenter'}; } } print "Finished Center ", time - $start , " secs\n"; my $path = cwd; my $out_file = "$path/word_ole.doc"; $out_file =~ s{\/}{\\}g; $doc->SaveAs($out_file); $doc->Close( { SaveChanges => $wdc->{wdDoNotSaveChanges} } );

I have timed this on three different computers. On the new one it takes around 50 secs to enter data and 70 secs to center data. Whereas on the others enter and center takes around one second each, which is what I was used to.

    It looks like I'm with the 'others' :-)

    Hope the other replies help you identify what's happening.

[Corion]: Hmm - actually, I don't need them, even though they'd be nice. I just want the (say) 10 latest images, and that's easily done with a limit 10 offset 0 clause, as I don't need all top 10 images for all users.
[Corion]: erix: Sure, but this is for a really-lightweight application and I'm replacing a CSV file / JSON file for user configuration with SQLite (and optionally, Pg) :)
[erix]: isn't a texty format handier for configs?
[Corion]: So far, I've avoided having even a user database by storing the user information in a (signed) cookie that the browser keeps for me, but as I want to be able to lock users, I need a second storage option :)
[Corion]: erix: It's needed for keeping the list of users and the list of tags associated with an image, and for keeping the images with users. I want an easy way to know if an image can be deleted, which means that it can't be referenced by any tag anymore. ...
[Corion]: SQL feels like a natural choice here :)
