possible problem with expression based library fields.
« on: August 04, 2006, 04:52:22 am »

image tagging, primarily using panes+tagging mode has become extremely slow with build 47.

if I tag a single person, MC is taking 3 seconds from click to tick
if I tag 5 people, MC is taking almost 10 seconds from the final click, to tick
standard type fields are also 3 seconds from click to tick

Having the tag window open or closed appears to make no difference. (the above timings were with it closed)

The first pane in this 11 pane view scheme is an expression based calculated field based around filenames:

if(isequal([filename (name)],kod,8),Kodak,if(isequal([filename (name)],img,8),Canon,if(isequal([filename (name)],scn,8),Scanner,if(isequal([filename (name)],tra,8),Tracy,if(isequal([filename (name)],mum,8),Mum,if(isequal([filename (name)],jas,8),Jason,Various))))))

It looks like so: (I added the [camera] field for testing and comparison)


If I do not filter by source, there is slowdown, but it's barely noticeable. However, filtering by source is what's causing the dramatic slowdown mentioned above. Neither changing to an expression based pane, nor turning of bi-directional filtering made any difference. the slowdown remained.

Could you send a library backup that uses this view?  I'll see if I can reproduce it. ( matt at jriver dot com )

Thanks.

Marko, I can't reproduce this with audio files. I have an expression-based field (the expression is about a page long in word) and it only takes a second or two to do what you described in MC12.

Could this be a problem with image tagging only?


Woops I was using the AW tagging system.

I can confirm this (using tagging mode/panes)... and it's not just for image files.
