在压力测试之前，怎样预估当前网络是否满足并发数的要求，能够举个例子详细说明一下吗？谢谢！

可以根据单一脚本的数据量统计后，推算出实际的流量大小。

You plan to run a 1-hour load test with a single user type. The user type will execute
approximately 5,000 sessions during the hour. We are also told that the available network
bandwidth is 1.5 Mbps.
After running a Baseline test, you read from the Baseline Report that the user type has a Session
Time of 47 seconds and an actual bandwidth of 1.56 KBps for the data sent and 5.3 KBps for the
data received.
First, determine the number of virtual users that are going to run.
#VU = (5000/3600) x 47
#VU= 65.3
#VU = 66
The total required bandwidth for one virtual user is
ReqBW = 1.56 + 5.3 KBps
ReqBW = 6.86 KBps
Let's convert the ReqBW from KBps to Mbps
ReqBW = (6.86 x 8)/1024 Mbps
ReqBW = 0.054 Mbps
The total required bandwidth for all the virtual user running under that user type is
Total ReqBW = 0.054 x 66 Mbps
Total ReqBW = 0.054 x 66 Mbps
Total ReqBW = 3.56 Mbps
