16:20 <rwilliams[m]> Is there something like 'time' for windows so i can see how long a cmd line process takes?

16:20 <rwilliams[m]> I'm trying to compare jruby startup times in native windows vs inside WSL2

16:22 <enebo[m]> Jyrki: I have not even tried it past 8 so it likely requires some add-opens for jruby-core -> javafx module

16:22 <rwilliams[m]> Looks like i found this for power shell Measure-Command {start-process whateveryouwantexecute -Wait}

16:24 <Jyrki[m]> <enebo[m] "Jyrki: I have not even tried it "> Is this something I can set somehow via a java cli arg?

16:27 <enebo[m]> Jyrki: yeah and with .jruby.java_opts as well

16:28 <rwilliams[m]> So 'rails routes' takes 20 seconds with --dev and 27 seconds without it on Windows 10. It was 15 seconds with --dev in WSL2 and 22 seconds without. Do these startup times seem normal? It's killing me for running rake/rails tasks

16:28 <enebo[m]> Jyrki: trying to find wiki page since I believe we have updates this

16:28 <enebo[m]> rwilliams: it sounds somewhat slow to me but I always feel windows is slower FS-wise so I guess it depends

16:29 <enebo[m]> Jyrki: https://github.com/jruby/jruby/wiki/ConfiguringJRuby

16:30 <rwilliams[m]> I'll give it a whirl on my mac later. But it's a lot slower of a machine than my windows machine.

16:30 <enebo[m]> Some times Java itself in warnings will tell you the CLI command to add but with .jruby.java_opts you can add those and not have a massive command line

18:23 <rwilliams[m]> just installed jruby from rbenv on mac os catalina and i'm getting this

18:36 <havenwood> rwilliams[m]: Curious to sanity check that you're really on 9.2.9.0? Did you have an earlier JRuby installed?

18:37 <havenwood> rwilliams[m]: No reason to think it's involved, but I usually suggest an `rbenv rehash` with rbenv for good measure.

18:39 <rwilliams[m]> @heavenwood

18:39 <rwilliams[m]> how to you @

18:40 <rwilliams[m]> havenwood: I reshashed too.

18:43 <rsim[m]> Found the JRuby issue https://github.com/jruby/jruby/issues/5969 which probably is causing these illegal access errors in JRuby 9.2.9.0

18:43 <havenwood> rwilliams[m]: Thanks, so it really is JRuby 9.2.9.0 with OpenJDK JDK 13.

18:44 <havenwood> https://github.com/jruby/jruby/issues/5913

18:53 <rwilliams[m]> havenwood:

18:53 <rwilliams[m]> havenwood: Thanks

20:01 <rwilliams[m]> enebo: I did some bench marking for WSL2/Windows/OSX/Docker for 'rails routes' on my app. https://gist.github.com/rwilliams/a4201e142c72239ddd4ac7c7dccb9d50 I guess it's just something i'll have to get used to unless i can somehow integrate something like Nailgun into my docker workflow

20:09 <enebo[m]> rwilliams: on native windows (not WSL) some of that is that we use Java IO and not native IO and because of this we also have an explicit \r\n handling. WSL2 speed I have no answer for. drip might be worth a try vs nailgun which traditionally have had some issues with IO

20:10 <rwilliams[m]> enebo: I'll give drip another go today

20:11 <enebo[m]> rwilliams: personally I have always felt windows FS as not doing well with lots of file opening

20:15 <headius[m]> And this was on wsl also?

20:15 <headius[m]> Which is slower

20:45 <rsim[m]> headius: Could you look at my comment at https://github.com/jruby/jruby/issues/5969 and confirm that we get the same known issue on Java 11 and getting "illegal access" for some public methods?

21:05 <rwilliams[m]> @he

21:07 <rwilliams[m]> headius: Windows is slower that WSL2, WSL2 docker is a decent bit slower than WSL2. WSL2 was faster than my macbook pro. Docker on the macbook is terrible but this is a known issue.

22:58 <rwilliams[m]> I'm trying to build nailgun and I'm getting Buildfile: build.xml does not exist! I'm using the jruby:9.2-jdk docker image

23:15 <rwilliams[m]> I'm trying to use jruby with nailgun and I get /opt/jruby/bin/jruby: line 488: org.jruby.util.NailMain: command not found
