Following on from my last post regarding sandboxing chrome / chromium ive found that If you start google-chrome with:
/opt/google/chrome/google-chrome --purge-memory-button --enable-seccomp-sandbox %U
Then, pressing 'SHIFT-ESC' will bring up a dialog window.
Pressing the 'Purge Memory' button will release memory on a sluggish PC. And of course will enable seccomp sandboxing. Try it to see if it helps.
