I find that the length of the script is one factor of the load. As we know the Vuser is loop the script from the begining to the end by order, not by random, so if your script is more longer ,then loop time is more longer. My question is :
1.How long is beter of one action's script?
2.How many actions is beter in a script?
3.long script in a LR script file and munch file with short script ,which is beter
There seems to be a confusion with basics here. All these things are scenario dependent. The question can be - "what is recommended? Single action or steps split into multiple actions". I will leave answering this to others.
I agree with Pankaj. For the last seven++ years of using loadrunner, business requirements have dictated both the content and complexity of my scripts, nothing else. After all, you are using this tool to address business questions.
Heck, I have one script that I am working with right now that includes ~1800 lines of hand tuned code in the form of custom functions, in addition to the 200 +/- derived from the original recording of the business process. It has a high degree of complexity and is still able to drive the system on an individual virtual user basis far faster than any human is capable of doing so.
