    Multi-threading Stable

    ProfessionalUwU released this 2023-06-29 02:15:53 +02:00 | 14 commits to main since this release

    Multi-threading

    Speed

    While testing with a variety of workloads we found that the program was up to 3 times faster than before.
    It took about 6 minutes to checksum 700Gb of varying data. Which is just impressive.

    CPU load and drive speed

    Chksum is now fast enough that your hardware will most certainly be the bottleneck. We maxes out our 2.5Gbs SSD no problem. It also used about 50-60% of the CPU.
    If the SSD was faster we would probably hit a CPU bottleneck.

    Scaling

    With this update the space and time complexity of the program is now linear with file count.
    Chksum will try to checksum all files at the same time so be careful with how many files you have.
    Memory also grows with how many files are put into the Dictionary.
