After Effects not using all of my RAM while rendering

Question

I have 8 gigs of RAM (which I know is not enough for the application) but I'm performing a very basic task with some animation, and while After Effects is using only 3-5% of my RAM.

I have allocated 6GB for use in the Memory settings and it's not utilising it which is making me end up with very slow rendering speeds.

Also, for a few seconds when I started my render, it showed that it was using 25-35% of my RAM and it was evident with the speeds but then it dipped down to 3-5% again in like 5-6 seconds.

Without any info on the contents of your project, the comp settings, render settings, system info etc. none of this means anything. Contrary to the myths that have polluted the Internet fo two decades things don't go faster in AE just with more RAM. File I/O does matter and a slow disk can kill any render speed. Likewise, uisng a single poorly optimized effect can cause AE to slow to a crawl. Things just aren't that simple and there are many factors to this complex equation. Depending on the situation what you see could be perfectly normal.
