I've done a bit of testing.....
I set up some basic shapes and outlined text similar to your file.
Ran the default action to Delete all Unused items.
This deletes all unused swatches, symbols, styles, brushes, etc. and can have an effect on file size.
Saved as an AICC EPS. The best I got was a 1MB file. I would guess that the additional 1MB you are seeing is due to the unused panel items. Run that action and try resaving. Before deleting the unused items I do see approximately a 1.9MB EPS file.
Then I saved the file to AICS6 and opened it there.
Ran the delete unused item action and saved as an AICS6 EPS... file size 400k.
Same exact file. The only difference is version if AI in use.
It would appear as though AICC merely saves larger EPS files. You would need to ask Adobe why.
The only way I was able to get a decent EPS file size using AICC2017 was to save to an Ai8 EPS file. This resulted in a ~250k document.
Now the AI8 format throws away a lot more data, especially metadata, than newer EPS formats. It's feasible that the newer formats are embedding additional PDF compatibility, color profiles, etc. Only Adobe would be aware of the actual variations in their EPS file formats.
Just commentary...... Note that I, personally, always save EPS files to AI8 format. I've yet to see any reason to use a newer EPS format if EPS is needed. But then, I haven't been an XPress user for many years. Last I saw XPress didn't work with .ai files. In addition, I dislike the CC versions of AI and also prefer to work in CS6 as much as possible in spite of the issues it sometimes has. Add VectorScribe to AICS6.... and it's pretty much on par with CC2017 in my experience.
