Onyx is kool for some things but it will not de-frag the hard drive.
And if you have not done a de-fraging in a while, the symptoms you describe
(taking a long time to save projects) sounds a lot to my ears like a hard drive that needs this done.
There are several 3rd party tools for this. I used to use ‘iDefrag’ before I
changed all my spindle hard drives to SSD’s (which do not need de-fraging)
Good Luck!
