Description Joris 2022-02-16 23:58:34 PST

The WebKitNetworkProcess process allocates 85 GB.

/proc/<pid>status shows :

VmPeak:	117607928 kB
VmSize:	85772212 kB

The parent process is xreader (a PDF document viewer) which indeed links to WebKit.

Hi, that's just virtual memory required by JavaScriptCore's Gigacage. Note that is *virtual* memory, i.e. address space. This is needed to maintain segregated heaps for different object types. It doesn't actually consume resident memory.

I'm impressed the xapp developers made the app work on macOS. They weren't kidding about their apps being cross-desktop. Honestly, I didn't know that it was still possible to build WebKitGTK on macOS at all!
