It uses a Solaris Porting Layer (SPL) to provide a Solaris-kernel interface on Linux, so that unmodified ZFS code can execute. 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). Tracing ZFS operation latency.

This work is latency critical, because volume IO is blocked until it is complete. Larger cells have better tolerance of tail latency (e.g. Studies across three decades have found that software, operations, and scale drive downtime in systems designed to tolerate hardware faults. Cells have seven nodes. Before and After.

This isn’t true (more on that in a follow-up post), and sites which are built this way implicitly require more script in each document (e.g., The server sends it as a stream of bytes and when the browser encounters each of the sub-resources referenced in the document, it requests them. for router components).

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

When we released Always On Availability Groups in SQL Server 2012 as a new and powerful way to achieve high availability, hardware environments included NUMA machines with low-end multi-core processors and SATA and SAN drives for storage (some SSDs). As we moved towards SQL Server 2014, the pace of hardware accelerated.

Few things within a home are restricted–possibly a safe with important documents. When more complicated routines are required to meet the needs, how does someone allow for changes without writing code, if they are allowed to? Until we acknowledge that hardware put in a home is different from a cloud service, we will never get it right.

There is no code or configuration change necessary to capture data and detect existing services. Lift & Shift is where you basically just move physical or virtual hosts to the cloud – essentially you just run your host on somebody else’s hardware. We let the OneAgent run and then leverage the data for the following key use cases.

Have we optimized enough with tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, progressive hydration, clients hints, HTTP/3, service workers and — oh my — edge workers?

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers? It’s much easier to reach performance goals when the code base is fresh or is just being refactored.

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers? Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms.
