Huh, I'd thought that Chromium used tcmalloc instead of system malloc, but turns out it only does that by default on Linux: https://chromium.googlesource.com/ch

Huh, I'd thought that Chromium used tcmalloc instead of system malloc, but turns out it only does that by default on Linux: https://chromium.googlesource.com/chromium/src/base/+/master/allocator/ https://chromium.googlesource.com/chromium/src/base/+/master... Does anyone know why? I could understand tcmalloc everywhere, or system malloc everywhere, but tcmalloc on just Linux seems odd. It's not like the Windows and OS X mallocs have any better reputation of efficiency than glibc malloc.
