Question

我现在正在努力研究Jruby on Rails。我们之前没有配置min / max jruby运行时，门户网站运行良好。

在这些日子里，我发现设置这些配置会提高门户网站的性能，所以我决定以这种方式配置它：

config.webxml.jruby.min.runtimes = 2
config.webxml.jruby.max.runtimes = 4

但是，我设置这个后门户无法启动，日志继续抛出java类找不到错误：

jruby.home: file:/var/tomcat/webapps/ROOT/WEB-INF/lib/jruby-stdlib-1.6.1.jar!/META-INF/jruby.home

设置这个min / max jruby运行时有什么区别？任何人都可以让我离开这个？

提前致谢。

jruby thread safe comparison

在config / warbler.rb

中

config.webxml.jruby.min.runtimes = 1
config.webxml.jruby.max.runtimes = 1

和config / environments / production.rb

config.threadsafe!

设置jruby min运行时发生了什么？
