I have files shot on a Canon Vixia that are MTS. I need to get them compressed and onto my website in mp4 format. (I have an online storyboard where my clients can pick the scenes for the edited video, but I upload greatly compressed clips). My normal workflow is to run them through EditReady to convert to mov and then compressor to compress and convert to mp4. I already converted through EditReady. I dropped them into compressor on Wednesday around 6pm and they still weren’t done by lunch today on a Mac Pro trash can.
I reduce from 1080p to 720p, reduce the bitrate, and convert to mp4 during the Compressor step.
Anything obvious I’m doing wrong or some way I can do this quicker?

Nothing you’re doing is inherently wrong. The Trash Can has Xeon processors so it doesn’t have hardware accelerated encoding so H.264 encoding is very slow compared to a comparable MBP or iMac. Even the 2017 iMac Pro, which is also Xeon, hooks into the GPU to do hardware accelerated encoding.
With the Canon Vixia MTS you’re likely encoding H.264 to H.264 which is going to be slow allow around (decode and encode) compare an i7 or i9 processor with integrated GPU.
MOV is a container, not a codec. If it’s H.264 MOV it’ll still be slow going comparing to ProRes MOV but that’s still another conversion compared to just re-wrapping (which is what you might be doing in EditReady.
