GC.Collect: Whatever doesn’t kill you makes you stronger

Just a meme that was bouncing around the office this morning, in relation to the nasty side-effect of calling GC.Collect explicitly in code: promotion of everything that doesn’t get collected.

What this means of course is if you call GC.Collect way before you get any memory pressure, objects will get promoted to L1, then to L2, and quite likely not get cleaned up for a long, long time, if ever.
