If there are some slow clients who are requesting pages, Then Apache children will have to wait until each client download the page which will result in Apache running more children which in turns consumes more memory and CPU ... not to mention that you'll be processing extra pages with the old ones.

I don't have the full picture, you are more capable to decide ... but as I said if it didn't work or if it turns out to be bad, then disabling it is very easy and won't take much time.
