Investigate memory usage on obfuscated sites

[FLamparski]

Seriously, all those useless nested spans surely take up a lot more memory than they need to.

This is indeed a potential problem which needs to be investigated further. However, the overhead of the initial rendering of say, 10-100% DOM nodes, all of which are completely passive, never read nor written again, should be orders of magnitudes less memory/CPU-heavy than this sweet text editor in which your users type their comments.
