The memory space is overwritten, to prevent retrieval. It's not deleted, hence no additional free space is gained.
This is a security feature, not a maintenance task.
It also uses CPU cycles and there's a performance hit for it.
Albeit small, but still takes work to do.
It will not increase device performance during or after it's been run.
Any perceived performance increase is nothing more than placebo effect.
