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.

Behind these perfect moments of entertainment is a complex mechanism, with numerous gears and cogs working in harmony. Replay traffic testing gives us the initial foundation of validation, but as our migration process unfolds, we are met with the need for a carefully controlled migration process.

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.

Combined with (delayed) advanced graphics APIs and threading support, WebXR enables critical immersive, low-friction commerce and entertainment on the web. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience. Offscreen Canvas. TextEncoderStream & TextDecoderStream.

Lower latency as a result of fewer service calls, which means fewer errors for our visitors. Each step of the flow serves a distinct purpose.

Once the generator is running, it processes the requests in the queue to compute the simulated pages. Generated pages are then persisted to an S3-backed Hive table for metrics processing.
