- danielheath 6y agoThreads are still going to make syscalls into kernel code, so... not as much, no.
- pjmlp 6y agoYou are better with processes per core, with no threads.
- remram 6y agoThis prevents the application's thread from moving cores, but doesn't prevent an unrelated thread from using that core (especially in a hypervised environment). That unrelated thread could still perform those attacks against the application's thread.
