v0.30.0

Compare Source

Changed

• Optimized wasmi bytecode memory consumption. (https://github.com/paritytech/wasmi/pull/718)
  • This reduced the memory consumption of wasmi bytecode by organizing the instructions
    into so-called instruction words, effectively reducing the amount of bytes required per
    wasmi instruction 16 bytes to 8 bytes.
    There was an experiment with 4 bytes but experiments confirmed that 8 bytes per instruction
    word was the sweetspot for wasmi execution and translation performance.
  • This did not affect execution performance too much but we saw performance improvements
    for translation from Wasm to wasmi bytecode by roughly 15-20%.
• Optimized call and return_call for Wasm module internal calls. (https://github.com/paritytech/wasmi/pull/724)
  • wasmi bytecode now differentiates between calls to Wasm module internal functions
    and imported functions which allows the wasmi bytecode executor to perform the common
    internal calls more efficiently.
  • This led to an execution performance improvement across the board but especially for
    call intense workloads of up to 30% in some test cases.
