Zen-cart 性能测试

[赵班长]

查看了本站所有版块，没有发现性能测试和优化方面的版块，不知道该站是否做过，总之Zen-cart在性能方面存在很多很多的疑问。

例：我使用apache自带的ab测试工具测试zen-cart发现：
Benchmarking 192.168.0.203 (be patient)
Finished 173 requests


Server Software: nginx/0.8.54
Server Hostname: 192.168.0.203
Server Port: 80

Document Path: /oxshop/index.php
Document Length: 41173 bytes

Concurrency Level: 1

Time per request: 173.627 [ms] (mean)
Time per request: 173.627 [ms] (mean, across all concurrent requests)
Transfer rate: 233.88 [Kbytes/sec] received

此时服务器性能如下：
top - 01:16:55 up 12 days, 6:12, 2 users, load average: 2.46, 8.93, 46.00
Tasks: 208 total, 4 running, 204 sleeping, 0 stopped, 0 zombie

Swap: 4030456k total, 76k used, 4030380k free, 764292k cached

难道zen-cart性能真的这么差吗？我们再来看看另一个测试工具webbench:

[root@Web-Server includes]# webbench -c 100 http://192.168.0.203/index.php
Webbench - Simple Web Benchmark 1.5
Copyright (c) Radim Kolar 1997-2004, GPL Open Source Software.

Benchmarking: GET http://192.168.0.203/oxshop/index.php
100 clients, running 30 sec.

Speed=770 pages/min, 406926 bytes/sec.
Requests: 385 susceed, 0 failed.

此时服务器性能如下：
top - 01:17:58 up 12 days, 6:13, 2 users, load average: 24.63, 12.51, 44.63
Tasks: 308 total, 103 running, 205 sleeping, 0 stopped, 0 zombie
Cpu(s): 84.1%us, 12.3%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 3.6%si, 0.0%st
Mem: 2010428k total, 1694988k used, 315440k free, 174708k buffers
Swap: 4030456k total, 76k used, 4030380k free, 765468k cached

问题出现了，为什么两个测试工具的区别这么大呢。CPU占用率为什么一直很高呢。

声明：首先排除Web服务器和硬件的问题，因为我测试了康盛的东西，都很正常。
第二排除mysql的问题，我做了优化，而且没有慢查询。

我询问了开发人员。zen-cart开始会把所有数据查询出来，然后存放到数组中，以后对数组进行操作，这可能是CPU占用率很高的一个因素。

期待官方人员给出回答，并粘贴官方的测试数据，测试工具。和优化。

期待我们真正的深入zen-cart而不是，下个中文版，装个模板，改改就开始用了。

期待网站开设性能方面的版块。

你是用本站下的软件测试的吗？
看看zen-cart.cn的测试数据吧，测试同时处理200个请求，速度并不慢...
这还是未做过优化的zencart，如果使用目前的几个缓存优化模块，有些页面能提高效率 50% - 80%
