Just recently measured: when doing a bulk-load of a DB that's larger than RAM, it's faster to turn off WRITEMAP and just use regular writes.
Doesn't that depend on the ratio of change compared to the size of RAM or
DB?
Read and think before you post. You have no idea WTH you're talking about, but you could easily have read the code or docs or papers before posting and actually known something.
I cannot follow your reasoning why you think that I don't think, and what convinced you that I have no idea what I'm taking about.
Wasn't it you who made some vague performance statement/recommendation without presenting any numbers or details on the tests one might assume you have made before writing?
There is nothing vague about "bulk-load a DB that's larger than RAM."
I also don't see why I should read your code just because you made some statements I cannot follow.
If you aren't going to do the basic homework then you have nothing to contribute.
