Should I be getting better render times with my setup?

Hello all, so not sure if this is the appropriate forum for hardware related stuff, but I feel like I should be getting better render times on the computers I have.

I'm rendering out a 17 minute video which has two tracks in Vegas 13, and I'm getting a pretty long render time regardless of the codec I use (wmv, avi or either of the mp4 options), and on either machine, both machines give about an hour and a half estimate, I rendered on my server to be able to use my laptop though, and it's only at 50% after half an hour, not sure if my laptop would have done the same.

My laptop has a Core i7 4720HQ and 16gb of ram, which gives vegas 8 threads it can use at roughly 3Hhz, though using CUDA only gave about 10% usage, this video doesn't have any special effects or anything on it, which from what I've found is what gpu acceleration is really used for.

My sever has two Xeon X5670 processors and 72gb of ram giving Vegas a total of 24 threads to use at 2.93Ghz, no GPU.

For my server it's able to use about 70% of my CPU resources without turning off my cctv software, if I do this it can use 85% but it didn't seem to impact render time much at all even after a good 5 minutes.

Now, this video does have a lot of sections where I am speeding up the footage 4x to skip boring parts, and the content is all at 30fps, rendering to a 1080p file using the stock settings in the mp4 presets, except for setting quality to best under the project settings tab.

I swear that I've gotten better rendering performance out of each of these machines in the past, I can't remember a video ever taking this long to render that wasn't a fair bit longer than this one however it has been a while since I've edited.

The one thing I can think of is if speeding up video 4x is really that intensive? Perhaps that's a lot more difficult than if you are just putting various clips together, but I'm hoping to see if this is about right based on the hardware setups, if vegas just really does need higher frequency cpu's because it's more single threaded optimized, or if something might be playing up causing this to take so long.

Dollars to donuts it's youraccelerstion and FX. Turn 'em all off and compare your times.

If you want faster rendering, then you might have to consider a current release version of Vegas, which gives you Intel QSV and nVidia nvenc support options. Whilst this current version 15.321 is still buggy, it does work and a new update is apparently being worked on

While speeding video, try to disable resample video in event properties. The later versions of Vegas are able to disable it globally in project properties. Resampling video does merging multiple frames into one instead of skipping them simply.
