  • Web load performance (tested with loader.io)

    From Noisome@VERT to All on Tue Nov 18 02:23:29 2014
    I just used a web load performance utility loader.io.

    SBBS web performed fairly well. It got up to 66 connections per second (4000 connections over a minute test) before it failed (crashed/sigsegv). 3000 connections test went with only 0.6% errors. 2000 was a perfect run.

    I just tested loading my homepage which is very minimal, 5.1kB.

    Though I am still concerned about the crash.

    If you provide a callstack dump, that'd be helpful in resolving the crash: http://wiki.synchro.net/howto:gdb

    No, I think that'll do it, but since the web server is really Deuce's baby, I've cc'd him the GDB info and hope he'll chime in.

    Looking at the crash dump highlights an issue with how the RNG is seeded... I plan on taking a look at that after the next release (it's a complex, far-reaching issue).

    As for the crash, it's "A JavaScript Thing". Older versions of js_rtpool.c weren't completely compatible with new changes in Seamonkey. If your js_rtpool.c is old, that could explain this crash. If not, I may have to cobble together a Linux box to test on and reproduce this issue.

    It was a fresh compile on Nov 11, and has a date which matches the CVS date:

    whats your avg response time in ms

    i had 250 clients in 1 min and got 228ms and 0% errors on apache
    i had 205 clients in 1 min and got 6945ms and 44% errors on synchweb

    ewwww

    whats sad is the apache box is a vm with 200mb of memory on a dual core host, the bbs box is on an atom with a gig of ram.

    bbses.info on apache had 18ms 0 errors, and it was under a heavy load doing other stuff at the time i tested it.

    my sbbsctrl didnt crash, but it did freeze up the entire computer during the tests

    Were you loading the same static page, or by "synchweb", do you mean the stock index page vs. "something else" on Apache.

    Also, what is the "MaxClients" setting in the [Web] section of your sbbs.ini file?

    Rats, JS crashes are the worst. I'll try to shake loose some time to repro and
    see if I can fix it.

    (crashed/sigsegv). 3000 connections test went with only 0.6% errors.

    i had 205 clients in 1 min and got 6945ms and 44% errors on synchweb

    I got 3990 clients in 1 min, 179ms and 0 errors on a static image (6.8KiB) from
    sbbs over my cable modem. That cruised along at around 80 clients, and it looks like my bandwidth was the limit, not Synchronet (which topped out at about 60% of one CPU worth of utilization).

    With my mostly stock index page, I got 3980 in 1 min, 288ms and 0 errors.. tended to run around 90 clients and cruised at 260% CPU, and bandwidth was the limit again (about 30MiB/sec on both runs).

    MaxClients is set to 1000 on my system.
