There's also a ZFS send/recv code path that should try to use the TASK_INTERRUPTIBLE flag (as suggested by a coworker), to avoid a kernel hang (can't kill -9 the process). On Linux, containers are a combination of namespaces (restricting what a process sees) and cgroups (similar to Solaris resource controls).

Windows has long had a reputation for slow file operations and slow process creation. This weeks’ blog post covers a technique you can use to make all file operations on Windows run at one tenth their normal speed (or slower), in a way that will be untraceable for most users! Have you ever wanted to make these operations even slower?

So far I’ve read a gazillion blog posts about people’s experiences with these AI coding assistance tools. And since this setup process was so new to me, I had a hard time thinking about how to phrase my questions. Or even if you haven’t yet, then you’ve at least heard about these tools in your newsfeed over the past year.
