- Avoid directory scanning for .ini files by restoring already initialized config cache state on the workers - Avoid directory scanning for modules by restoring already initialized modulemanager state on the workers - Avoid directory scanning for external profilers DLLs by disabling the option in the build config - 20s -> 319ms of FEngineLoop::PreInit which was caused by directory scan through XGE remote filesystem - 5% -> 96% efficiency when computing the effective work against process total time for remotely built shaders - 5m36 ->1m26s to run "recompileshaders all" console command including waiting on async built shaders #rb Danny.Couture (authored), Luke.Thatcher, Steve.Robb, Josh.Adams [FYI] Bob.Tellez, Danny.Couture #ROBOMERGE-OWNER: Arciel.Rekman #ROBOMERGE-AUTHOR: arciel.rekman #ROBOMERGE-SOURCE: CL 11106212 via CL 11106216 #ROBOMERGE-BOT: (v640-11091645) [CL 11106241 by Arciel Rekman in Main branch]
