camlow325 has quit [Quit: WeeChat 1.5]
<lopex> headius: had a question wrt that sprinf thing
<headius> donV: yeah, feels like we have fewer active resources lately and more to do :-\ I want to review that fellow's set of patches that get 9k working
<headius> it sounds like it wasn't as bad as I expected
<headius> lopex: sure, what's up

<headius> oh, I'll tell him to join

<lopex> oh
<lopex> no bots
<lopex> is that an idiom ?

<enebo> lopex: I never use those but that is how we do it on travis
<enebo> lopex: so I am guessing if you look at travis file there might be a way
<lopex> how do you doit usually ?
<enebo> lopex: this was an mri test right
<lopex> so what's the command ?
<lopex> I'm sorry I'm bothering you with things like that
<lopex> :P
<lopex> btw
<lopex> it was fixed but imagine the impact
<enebo> bin/jruby test/mri/runner.rb test/mri/ruby/test_sprintf.rb (or whatever file)
<enebo> lopex: if you want to do excludes you can add: EXCLUDES=test/mri/excludes bin/jruby test/mri/runner.rb <test file>
<lopex> headius: you think jruby might me overusing the calls ?
<lopex> *be
<headius> lopex: I saw that perf problem years ago but never looked any deeper
<enebo> lopex: and TEST= env can be used to narrow things down more within the file
<headius> I backed off from using thread cpu time JMX call
<lopex> headius: also there this http://vmlens.com/
<lopex> headius: they claim you can rebug against races there
<lopex> headius: have an opinion ?
<enebo> lopex: headius: Isn't this getting fixed
<enebo> lopex: I think EC2 is addressing this on their own
<enebo> lopex: not that I guess other systems may not have the issue
<lopex> hmm
<lopex> weird
<lopex> I though it was a general problem
<lopex> enebo: so it might be a int/ext guess problem ?
<enebo> lopex: I might be looking at another performance issue
<lopex> *an
<lopex> so what should I do
<lopex> the backrefs is one thing
<enebo> lopex: but this is a Xen issue I think and will be addressed by patches
<lopex> ah
<GitHub122> [jruby] headius closed issue #4232: Memory leak in JRuby 1.7.25 https://git.io/vP1z8
<lopex> enebo: but it's determined by os call anyways right ?
<lopex> not hotspot or anything ?
<enebo> lopex: I think this is just because impl of those systems calls in virtualized envs sucks
<enebo> lopex: so people made workarounds to not suck
<lopex> mhm
<enebo> lopex: but now that it is being widely reported they are fixing it upstream
<enebo> lopex: your link almost implies whatever the JVM was doing no longer is doing it
<lopex> but otoh, it's insane to optimize aginst sys calls in general
<lopex> and then in virtualized env, the perf would differ
<enebo> lopex: I am confused why they link to the second article I posted but I did not fully read you link
<lopex> you'd need a matrix of functions and perfs for a system
<enebo> lopex: if you are running high perf workload on EC2 and it runs much slower than locally you figure this out and workaround it if it is not your code
<enebo> lopex: it is the way of the world :)
<enebo> lopex: it sounds like in this case it was a huge perf drop
<lopex> enebo: but all syscalls ?
<lopex> in venvs ?
<enebo> lopex: why? just profile your code and do something if something is wrong
<lopex> enebo: but what if you cant ?
<lopex> enebo: like time calls ?
<enebo> lopex: I don't know
<enebo> lopex: I need to go to store now afk
<lopex> enebo: from what I read those can matter just as much
<lopex> ok
<lopex> you can use faser apis that's what those blogs suggest
<lopex> but it can be a tip of an iceberg
<lopex> *faster
<lopex> and indeed those are pathological
<lopex> but can skew benchmarks for example
