What is Network Buffer?
Network buffer size sets the maximum buffer size that receives HTTP response from the server.
How does it impact my test?
If the size of response is huge, then the server will send data in chunks. This will be an overhead to the system when multiple Vusers are running. Default size of network buffer is around 12KB. Follow below mentioned steps to increase the size of network buffer.
- On a WIN 7 system, go to C:\Program Files (x86)\HP\LoadRunner\dat
- Open file called "WebAdvancedOpt.txt"
- Go to line which looks something like this "6="T_EDIT_NUM;Web;NetBufSize;Network buffer size; ..."
- By default, 12288 Bytes is the size of network buffer. This can be increased anything less than 32KB
