Will macOS Mojave 10.14 slow down an early 2011 13″ MacBook Pro?

I am currently running OS X El Capitan on my early 2011 13″ MacBook Pro. I am thinking of upgrading to macOS Mojave, but would like to know if it would slow my MacBook Pro because of my specs?

Please see more info on the specs below:

I’m not using an SSD and my current available space is 140GB (total is 320GB), though I always make sure I don’t go below 100GB available space.
