What do you mean by "other applications"?
- jeffbee 1y agoI mean when your application sends on a socket, the kernel may also send and receive traffic for another task while it's in the syscall, just for funsies, and this is true even if your applications are containerized and you believe their CPU cores are dedicated to the container.
- lxgr 1y agoAh, but that's an OS implementation problem, not one with TCP or QUIC, no?
- jeffbee 1y agoSure, but the ready appeal of QUIC is that it is in user space by nature, while Linux ties TCP to the kernel. You either need special privileges to run user space TCP on Linux, or you need a different operating system kernel altogether.
