Should I use "Bitrix Banner Advertising"?

Question

1C-Bitrix

The question is only for those who can really give a motivated answer and not assume.
Oddly enough, there are still sites that sell advertising on their project and this is the only way to make money

And that is introductory
Types of banners:
Picture,
picture + text,
html5
Depending on this, some of the fields are used, some are not, and here the standard functionality is practically suitable Banner advertising , although sometimes redundant.
There are 12 types of banners - everything seems to be fine
. Now about what you need
. Statistics are needed, in terms of functionality, we also need export to PDF and minor improvements such as a picture for the phone, but 90% will do.
The load is about 40K per day (and the last time I used this miracle, it was not cached from the word at all) or statistics or cache.

YES, at that moment there were blunders like z-index2 on the background in it, which was touching;)
And the main thing is to make everything work as quickly as possible "google page speed all things" and here anyway there are a lot of unnecessary things like display schedules and so on, which obviously the speed of processing will not affect positively.
Yes, and the size of the logs scares me.
At the moment, the logs for a banner per day are gaining about 20 MB and this is pure self-writing, it seems that the logs in the Bitrix will be slightly larger and will inflate the base a little more than a self-saved log on highloads?

in general, the question is whether it is worth using this monster and finishing it with a file, removing unnecessary functionality and adding, albeit a little, but still new.

Or is it easier to stir up everything on infoblocks?
