硒网格上的并行执行会影响执行时间吗

Question

I'm writing automated scripts to load thousands of records into the web application and the time frame in which data has to be loaded is very less. So I thought of using Selenium Grid to run the scripts in parallel to achieve lesser time. Now, My question is will this affect the execution time of the automated scripts or the hub machine. There will be around 20 machines or maybe even more connected to the hub.

Also, Is using selenium grid the best option for this or I could use some other approach as well. And, feeding data from database or using web services is not possible.

Thanks in advance.

Maybe. It depends on the rest of your stack. Is the underlying server multi-threaded; will each Selenium Grid instance be provisioned its own process on the server? What about your database - will transaction locking block the other processes? Will any of your servers hit some performance bottleneck? Is the database ACID compliant ? - Ie Will running multiple Selenium instances like this cause race condition errors?

There's only one way to know for sure: Do a trial run, and benchmark it.

If you have direct access to the database, then you could seed the data directly (using SQL, presumably). This would be much faster, if it's a viable option.

Also, it depends what you're typing to achieve here. Are you simply seeding the application with a tonne of data? (In which case, SQL is a better option.) Or, are you actually performance-testing the website? (In which case, intense parallel execution may be part of the specs.)
