我想为我的rails 3应用程序进行性能测试,我根据rails在线指南进行了尝试

rake test:profile

它给出了一些输出:

Specify ruby-prof as application's dependency in Gemfile to run benchmarks.
Loaded suite /usr/local/lib/ruby/gems/1.9.1/gems/rake-0.9.2/lib/rake/rake_test_loader
Started
.
Finished in 0.326233 seconds.

1 tests, 0 assertions, 0 failures, 0 errors, 0 skips

但根据指南,应该有类似的东西:

BrowsingTest#test_homepage (31 ms warmup)
           wall_time: 6 ms
              memory: 437.27 KB
             objects: 5,514
             gc_runs: 0
             gc_time: 19 ms

以及在app的tmp/performance dir中生成的一些日志文件,在我的情况下不存在.

性能测试是在我的应用程序的test\performance目录中生成的示例测试browse_test.rb:

require 'test_helper'
require 'rails/performance_test_help'

# Profiling results for each test method are written to tmp/performance.
class BrowsingTest < ActionDispatch::PerformanceTest
  def test_homepage
    get '/'
  end
end …

我当地的时区是PRC(中国),UTC + 8,但是

select (timestamp '2016-09-01 00:00:00' at time zone 'PRC') 
        -  (timestamp '2016-09-01 00:00:00' at time zone 'UTC');

回报-08:00:00.不应该+08:00:00吗？

我的PostgreSQL版本是9.5.
