You need a lot of software engineers and the willingness to rewrite a lot of software to entertain that idea. Here are the bombshell paragraphs: Our datacenter applications seek ever more CPU-efficient and lower-latency communication, which Pony Express delivers. The desire for CPU efficiency and lower latencies is easy to understand.

Whenever I paused for too long, ChatGPT would interpret what I said so far as my request and start processing it. Unpredictable wait times : Wait times (latency) for ChatGPT’s responses are unpredictable, and there aren’t audio cues to help me establish an expectation for how long I need to wait before it responds.

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). Here's some output from my zfsdist tool, in bcc/BPF, which measures ZFS latency as a histogram on Linux: # zfsdist. Tracing ZFS operation latency.

You’re half awake and wondering, “Is there really a problem or is this just an alert that needs tuning? Telltale learns what constitutes typical health for an application, no alert tuning required. For example, a latency increase is less critical than error rate increase and some error codes are less critical than others.
