Automated system maintenance timing

Question

iMac early 2008, 2GB RAM, 2.8GHz processor, HD 320 GB total, 225GB available, OS 10.6.8
Whilst researching various causes for a Mac running slowly, I came across the statement that automated system maintenance procedures are scheduled by default to occur in "the early morning" hours, provided that the computer is running 24/7.  If I were to leave my computer on, it would go into sleep mode, as would I, during these early morning hours (assuming this to mean 1am etc.). Do the automated processes indeed occur in the 1am range and if so, will they happen if the computer is in sleep mode?

Answer 1

Sorry that you feel that precision is not required in dealing with a modern
operating system, and that the obsolete answer appears to fit your ideas
on how to maintain a Mavericks system when compared to an older one.
On more than one occasion, advice has been suggested without bearing.
So be it with your interest in getting an answer that fits Mavericks 10.9
since the factors that did change for this new system, are not addressed
by the reply you sought to include as a correct response.
And, I also gave you a bonus tip on a historically correct (to Mavericks)
source of content that can be used with Mavericks for issues of a slow mac.
Too bad I wasted some time and research, on your behalf. If I weren't
working for free, I'd bill you double, and offer you to try a retail product.
Your understanding of an answer has not been helpful to a resolution.
However it does appear you did not read the link that supports my point:
This is current to Mavericks, cited by Pondini as of now:
On Snow Leopard 10.6.x and Later, if your Mac is powered-on but sleeping
during those hours, the scripts will run shortly after it awakes.
If you do not want current information on OS X 10.9.5, why ask and
accept info that was OK prior to Lion 10.7.5 & think that's current??
Is english your first language? I can try google translate if it helps...
Good luck and happy computing!
