Re: [bitbake-devel] hashserv performance issues

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Joshua reminded me of how to get the server stats (thanks).

For our public server:

$ bitbake-hashclient --address wss://hashserv.yoctoproject.org/ws stats
{
    "requests": {
        "average": 0.06250257539454776,
        "max_time": 16.712204183917493,
        "num": 381569673,
        "stdev": 0.18345958610620752,
        "total_time": 23849087.254955433
    }
}

Compared to my local system:

$ bitbake-hashclient --address ws://localhost:8686 stats
{
    "requests": {
        "average": 0.0004462178160857849,
        "max_time": 0.04537125899992134,
        "num": 3121,
        "stdev": 0.00163338261679226,
        "total_time": 1.3926458040037346
    }
}

For a world build with 38000 tasks, 38000 * 0.0625 = 2375 seconds or 39
minutes, so I suspect the hash server performance is a real issue here
:(

Michael: Is there anything we can do?

Cheers,

Richard
