Oxygen XML Forum

While trying to optimize our oXygen plug-ins and customization, I noticed a many temp calls by oXygen.

It seems there are many disk calls creating and deleting some kind of temporary image files.
%AppData%\Local\Temp\imageio######.tmp
(~25k calls on start-up taking 3.5 seconds, 7k on open document taking ~2 seconds)

Seems like an awful lot of IO overhead for temp images that are created and immediately deleted.

Just thought I might point it out as something to look into.
Might get some considerable performance/responsiveness improvement.
Could try to use memory only or have an image/icon resource cache.

Or is there some underlying reason it must use the file system and continuously reprocess 100's of images?

Thanks,

Hi,

Thank you for reporting this. We will analyze the temporary image files creation to see if this is indeed a performance issue.
We will notify you when we will have a conclusion.

Can you please tell us the type of the images you are using?

Best regards,
Mihaela.

Hi, thanks again for the quick reply.

The temporary images occur when opening a completely empty DITA Topic in Author view.
Its really just a minor thing that might be able to be improved.
The temporary images appear to toolbar and menu icons.

That's kind of why I just posted here under feature request.
It takes about 4 seconds for a empty topic to open and 5 seconds to checkout and reopen.
I figured with 2 seconds possibly being spent doing icon image IO,
there might be a way <oXygen/> could cut load time of small DITA topics in half.

There's probably a reason it reprocesses the icons to enable as disable them or something.
If it where me, I would try and set-up an Icon memory array or something that caches them the first time.

Thanks again, happy holidays and happy new year.

Forgot to mention in my original post:
Win 7 64 bit, <oXygen/> XML Author 17.1.0 Standalone, build 2015111718

Hi,

We reproduced the problem and we fixed it. The fix was to disable the disk cache used by the ImageIO library.

From our tests the performance improvement is between 5% and 10%.

Thank you!

PS:To determine the file activity we used logging and Java profiling, but I would like to find out what tool have you used for monitoring the file activity.

I use Process Monitor to capture system events.

Exported it to a spreadsheet, filtered by imageio, and summed the duration column.
I suspect we may see a larger improvement because of anti virus, encryption, and stuff.
That's a pretty decent improvement for opening small DITA topics with a small change as long as nothings adversely affected.

Thanks again for the super fast response.
