drnic @ starkandwayne1: marco, looks good
Marco N. @ Pivotal: cool
drnic @ starkandwayne1: added
pivotal room: Servcie Core update from Marco is now
drnic @ starkandwayne1: marco - your manifest fixes for registrar errand will go into upstream broker-registrar repo? being able to select which plans are public by default would be good
drnic @ starkandwayne1: shannon - cool re router access for brokers
drnic @ starkandwayne1: shannon super cool on multi ports
anonymous1 morphed into Sergey
drnic @ starkandwayne1: What is the URL to CAB call minutes/blog from September? Which blog is it going to?
pivotal room: @Phil can you update Dr.Nic on last month's blog
anonymous2 morphed into Marco(a)Swisscom
drnic @ starkandwayne1: To get GH issues for conversations, I think ppl need to "Watch" each repo https://github.com/cloudfoundry/go-buildpack
drnic @ starkandwayne1: https://github.com/cloudfoundry/go-buildpack/issues/22
drnic @ starkandwayne1: https://github.com/cloudfoundry/nodejs-buildpack/issues/32
drnic @ starkandwayne1: Are we going to continue using both Consul and ETCD?
drnic @ starkandwayne1: why?
drnic @ starkandwayne1: remote urls for releases is lovely
drnic @ starkandwayne1: to see added
Marco N. @ Pivotal: Nobody's talking about the elephant on the call
julz: there's an elephant on the call? [http://webconf.soaphub.org/conf/images/wink.gif]
shinichiNakagawa(a)NTT: mute: *6
Phil Whelan: @drnic I wasn't able to write up the notes last month. I sent a recording of the call to the cf-dev@ mailing list though
drnic @ starkandwayne1: amit, there is an existing bosh release for route-registrar https://github.com/cloudfoundry-community/route-registrar-boshrelease; perhaps promote it if you want it; else we can drop it
Chris(a)IBM: @phil, we'll let it slip just this once
drnic @ starkandwayne1: @phil oh cool re a recording; will go look
Deepak Vij: Question for Simon Moser regarding project Flintstone that talks about port to Ruby 2.2.3 & JRuby. It came to our attention that current CC component does not take advantage of multi-CPU/Cores environment. This may be due to the fact that Ruby MRI GIL provides thread-safety guarantees though at the cost of overall performance degradation. Is this the reason current ports to other Ruby versions are being looked at? Deepak Vij Huawei
Simon Moser @ IBM: @Deepak Vij: yes, thats one reason, although ruby 2.2.3 and jRuby are two separate issues. 2.2.3 is just "up to date maintenance", whereas jRuby really is aimed at improving performance
Simon Moser @ IBM: concurrency performance
Simon Moser @ IBM: I'll talk about the results and challenges so far when I get called out in the call
Deepak Vij: Thanks simon
Phil Whelan: @drnic to save you searching [http://webconf.soaphub.org/conf/images/wink.gif] https://www.dropbox.com/s/t8xewz5vw708b5q/cab_9th_sept_2015.mp3?dl=0
drnic @ starkandwayne1: thx
Simon Moser @ IBM: @Jim Campbell: can you confirm that , by changing UPD to TCP in the backend - that change won't affect any existing doppler firehose clients - correct ?
drnic @ starkandwayne1: perhaps a shared bosh-lite isn't best performance testing env
drnic @ starkandwayne1: jruby/jvm will want lots of ram to be happy?
drnic @ starkandwayne1: what performance improvements did upgrading to mri 2.2.3 give?
Simon Moser @ IBM: we didn't measure around 2.2.3
drnic @ starkandwayne1: drmax - There is an Others section in agenda
Simon Moser @ IBM: and the bosh lite isn't shared, its dedicated for this effort. We have two equal VMs, oneMRI and one jRuby to do the comparison, but this I agree this isn't an ideal environment (it was intended to give us a ballpark figure to make the decision, but we expected a bigger difference than 20%)
drnic @ starkandwayne1: Simon - I mean the host vm is shared amongst all warden containers
drnic @ starkandwayne1: garden
drnic @ starkandwayne1: and local networking, which you mentioned
drnic @ starkandwayne1: pretty quick to spin up dedicated CF - perhaps try terraform-aws-cf-install repo
Simon Moser @ IBM: got it - yes, we are aware of that. We thought it might be good enough for the ballpark, but maybe that was wrong
drnic @ starkandwayne1: MRI is constantly improving its performance
Simon Moser @ IBM: we should try that terraform thing
drnic @ starkandwayne1: And this comes from the person who promoted JRuby to the world during my time at Engine Yard
Simon Moser @ IBM: lol
Simon Moser @ IBM: and yes, we're aware of the MRI improvements - like I said, we expected bigger differences
drnic @ starkandwayne1: perhaps ping Jruby team - they might suggest some tuning
Simon Moser @ IBM: ok
