我做了 AB Apache 测试，看起来不错，但是当我加载我的网站时出现错误

Question

我有一个在线购物网站，我使用 WordPress、WooCommerce 和 W3 Total Cache。

我做了一个 AB：

    ab -l -r -n 600 -c 30 -k -H "Accept-Encoding: gzip, deflate"

我得到以下结果：

    Percentage of the requests served within a certain time (ms)
      50%    851
      66%    992
      75%   1664
      80%   2421
      90%   3442
      95%   4078
      98%   6122
      99%   6766
     100%  12808 (longest request)

看起来还不错，但问题是每天20/30次我得到一个请求超时错误，有时我会遇到其他错误。我联系了托管方，他们总是说没问题。我很困惑。我只想问...我的测试有问题吗？谢谢...
