Asp.net + Access 压力测试

今天来个了压力测试，环境如下:

语言: asp.net C#

Dll大小: 52kb + 260kb + 112kb + 20kb + 48kb=492kb

数据库: :Access 8MB左右 单连接访问数据库4-5次

IIS: IIS6.0 端口:80 限制:25%的Cpu利用率

应用程序池:独立

CPU: CM520 1.6Ghz x 1

内存: 2GB

实际占用: 28MB

并发 数: 30 持续60秒

网络: 本地网络

测试结果如下:

Average Click Time 219 ms, 1,536 Clicks, 0 Errors

Total Number of Clicks: 1,536 (0 Errors)

Average Click Time of all URLs: 219 ms

平均速度:219 在开始的10秒里，平均速度800ms,而后逐渐降低变为58ms

也就是程序是从800ms 逐渐提高到58ms....最后稳定在58ms左右。

//文字版的摘要结果如下:

Results of period #1 (from 4 sec to 15 sec ):

****************************************************************

Completed Clicks: 305 with 0 Errors (=0.00%)

Average Click Time for 1,800 Users: 863 ms

Successful clicks per Second: 29.61 (equals 106,584.86 Clicks per Hour)

Results of period #2 (from 15 sec to 25 sec ):

****************************************************************

Completed Clicks: 307 with 0 Errors (=0.00%)

Average Click Time for 1,800 Users: 61 ms

Successful clicks per Second: 30.14 (equals 108,495.23 Clicks per Hour)

Results of period #3 (from 25 sec to 35 sec ):

****************************************************************

Completed Clicks: 307 with 0 Errors (=0.00%)

Average Click Time for 1,800 Users: 60 ms

Successful clicks per Second: 29.89 (equals 107,607.40 Clicks per Hour)

Results of period #4 (from 35 sec to 46 sec ):

****************************************************************

Completed Clicks: 310 with 0 Errors (=0.00%)

Average Click Time for 1,800 Users: 58 ms

Successful clicks per Second: 30.09 (equals 108,325.99 Clicks per Hour)

Results of period #5 (from 46 sec to 56 sec ):

****************************************************************

Completed Clicks: 307 with 0 Errors (=0.00%)

Average Click Time for 1,800 Users: 58 ms

Successful clicks per Second: 29.76 (equals 107,136.94 Clicks per Hour)



图片其实挺清晰的，放大看还行。

对于这个曲线，我很郁闷，在10秒种的时候为什么会出现一个瓶紧，而且尝试过，最多50个并发连接，50个连接以后的，速度就要超过1秒了。

测试2，连接Access，不关闭Connection，等待连接池满。

结果Access只能并发50个左右的并发连接，超过50连接会出现连接失败的情况。
