Do you have a lot of packages installed and auto-loaded at startup? In
my experience, assuming Linux, this is most likely the cause of slow
starting, not Octave itself.
You can add the -f/--norc option to prevent octaverc scripts from
running and auto-loaded packages from loading. Or you can do "pkg
rebuild -noauto" for each package you don't need loaded all the time.
This may speed startup quite a bit:
$ time /usr/bin/octave -q --eval pi
ans = 3.1416
real 0m1.061s
user 0m0.964s
sys 0m0.080s
$ time /usr/bin/octave -qf --eval pi
ans = 3.1416
real 0m0.064s
user 0m0.044s
sys 0m0.016s

You could look at any of the solutions to run interactive processes from
within vim. I just found these with some quick searching, I have not
tested either:
