This wasn't a change of an entire codebase, only one portion of it (the tag engine). But more importantly, when only 6 web severs are running stackoverflow.com there's a decent chance a non-triggered GC happens stalling the servers in rotation anyway, granted this lessens the chance of a user-facing stall overall. Also, it complicates the build processes since that queue of rotating servers out gets involved, for example if 3-4 are in a GC rotation then 1-2 are starting the build loop, you're running only on 5 and 6, while that's fine and doesn't even hit 50% CPU, it's a little risky. Worse is you have the very real possibility of taking ALL servers down during a build and GC combo, which we'd never want to happen. |
