The wiki page should be corrected. Saying "lots of memory" is somewhat ambiguous. If this were the 90s, then it would be right.
As for the recommended amount of system memory, recommended amounts are not the minimum amount which code requires to run. It in no way contradicts my point that the code itself does not need so much RAM to operate. However, it will perform better with more until your entire working set is in cache. At that point, more RAM offers no benefit. It is the same with any filesystem.
