[Swftools-common] Inconsistent PDF processing time

[Matt Long]

I came across a PDF that took around 30 seconds to process with pdf2swf within my app. This was curious since it was a single page PDF (granted with a lot of graphics on it).

I ran pdf2swf manually on the command line to verify the time. The first time I ran it on the command line, it took a similar ~30 seconds to convert. However, I ran the conversion again (with the same parameters) on the command line a few minutes later and it finished almost instantaneously. Now every time I run it, it's speedy and I'm unable to reproduce the 30second runtime.

I assume something is being cached somewhere after the first run. Even if I change the input file name and move to a different directory, it's still runs quickly. Can someone please explain what's going on here?

I observed the same behavior on my desktop (fairly powerful Windows 7 machine) and a virtualized Windows Server 2008 machine.

I'm using pdf2swf v0.9.0

Here's my command.

pdf2swf.exe --fonts --stop --flashversion 10 sched.pdf -o output.swf

PDF in question is available here: http://www.caltrain.com/pdf/Holiday_Schedules/Caltrain_Weekend_Holiday_Schedule_08-31-2009.pdf

Thanks!

Matt
