    UCall

    Up to 100x Faster FastAPI. JSON-RPC with io_uring, SIMDJSON

    Most modern networking is built either on slow and ambiguous REST APIs or unnecessarily complex gRPC. FastAPI, for example, looks very approachable. We aim to be equally or even simpler to use. It takes over a millisecond to handle a trivial FastAPI call on a recent 8-core CPU. In that time, light could have traveled 300 km through optics to the neighboring city or country, in my case. How does UCall compare to FastAPI and gRPC? How can a tiny pet-project with just a couple thousand lines of...

    SPX

    SPX

    A simple & straight-to-the-point PHP profiling extension

    ...Very simple to use: just set an environment variable (command line) or switch on a radio button (web request) to profile your script. Thus, you are free of manually instrumenting your code (Ctrl-C a long running command line script is even supported). Using a dedicated browser extension or command line launcher. Multi metrics capable: 22 are currently supported (various time & memory metrics, included files, objects in use, I/O...). Able to collect data without losing context. For example Xhprof (and potentially its forks) aggregates data per caller / callee pairs, which implies the loss of the full call stack and forbids timeline or Flamegraph based analysis.

    KCP

    KCP

    A fast and reliable ARQ protocol

    ...It is implemented by using the pure algorithm, and is not responsible for the sending and receiving of the underlying protocol (such as UDP), requiring the users to define their own transmission mode for the underlying data packet, and provide it to KCP in the way of callback. Even the clock needs to be passed in from the outside, without any internal system calls. The entire protocol has only two source files of ikcp.h, ikcp.c, which can be easily integrated into the user's own protocol stack. You may have implement a P2P, or a UDP-based protocol, but are lack of a set of perfect ARQ reliable protocol implementation, then by simply copying the two files to the existing project, and writing a couple of lines of code, you can use it.
