The actual preview video file was 2.74 MB. And it appeared to only be using 25% of the computer processing power during production. Usually when producing, it uses 90%+ of the cpu.
here are the production specs:

I am also seeing the severe drop off of rate-of-production; also CPU usage falls way off [watch task manager]
can you tell us about your PC system specs?
do you have a browser open during production?
I've been seeing noticeable adverse affects when browsing while producing
I’ve seen several posts regarding slower production times
with Camtasia 9. I can never understand it myself.
Ever since the very first
beta build of Camtasia 9 I’ve had faster production times with all of my
I ran some tests today to benefit you and others as well. For what it’s worth here’s my results.
One thing I can tell you is this. I believe the default MP4
production setting for Camtasia 9 is video quality at 60%.
I reduced that quality to 50% in a custom production and the 50% setting sticks. Meaning that, when I changed it to 50% in custom productions the setting changed for default MP4 productions with the smart player to 50% as well. That 60% setting can increase render times.
However, even at 60% my render time in Cam9 is still faster than Cam8 at 50%.
I just ran some tests on an identical project out of curiosity. I’m going to post the results for you to see.
Processors have improved somewhat since I built my computer two years ago. But I wouldn’t say they’ve improved by leaps and bounds. I built my computer with a take no prisoners attitude toward video editing that has served me well. Aside from running multiple processors I’ve got a pretty strong build.

I also surf the web when while producing videos and it’s never caused me any grief.
The first two images are default Camtasia 9 and default Camtasia 8 productions. The callout indicates production type and production times in minutes and seconds. As you can see Camtasia 9 outperforms Camtasia 8 in every instance.
Custom productions with a smart player.
wish I could experience your outcomes; but after well over 500 MP4 w/controller productions [all involving upgraded CS8 projects] all I get are slower productions
my CS8 and CS9 specs are a little tighter than yours: 70% quality, 1 second keyframes, H264 high, audio 256 khz
I've always used these specs with CS8
I've made many A/B tests; always CS9 was slower
I reported this as a bug, provided tech support with sample projects; they confirm similar outcomes; they are investigating
your system is much more robust than mine, but the slow downs and browser stuff seemed to kick in when I started using CS9 betas builds that incorporated the current onyx controller; FYI, I drive a decent Lenovo i5 laptop w/8GB RAM, 235 GB SSD; Win 10 Pro; everything stays on the SSD
about half of these recent productions involved photo slide show JPG based 1920x1080 projects [high object count]; the other half have involved MP4 source projects cooked at 640x480 [very low object count], like 3x project duration ...
I've seen same trends with both types of projects; considering the small size of the 640x480 stuff, I am amazed at how slow they render
single trec based projects do produce fast; but those that involve many trecs also drag out
I'm stumped re the CPU usage fall offs; that must play a significant role here; and, I'm not using 50% of my RAM
because my main PC [Lenovo laptop] is in the shop, I'm using a 10 year old 32 bit Dell Vista desktop [2GB RAM, 25 GB available on system HD]
I had used this PC to do all of my screencasting until I got the laptop in Oct 2012
it had 8.0.0 already on it, which I upgraded to 8.6.0 for today's test
I just imported one of my current workflow projects and produced it using the same specs posted above, at dimensions of 640x480
the project was made from a single MP4 and ran 12 minutes in duration
the production finished at 13.5 minutes, and the CPU usage stayed at 80% the entire time
on my Windows 10 64 bit CS9 laptop, this project would have taken over 30 minutes to produce!
WHAT COULD BE GOING ON WITH CS9 PRODUCTIONS TO CAUSE SUCH POOR CS9 PRODUCTION TIMES?
I just wanted to update this thread with a link to a post that Kevin Liu wrote up on improving your rendering times with Camtasia 9:
