==================
I'm currently running a survey with 9 languages setup and I'm experiencing a much higher number of dropouts than usual.
I upgraded the server the system is running on to a dedicated server with 64GB of Ram and 8 CPU cores yesterday morning but the dropouts haven't improved overnight.
Would the number of languages affect the size of the session files and is there anything I can do/check to improve this situation?
Any idea roughly what the maximum number of simultaneous connections I could hope to achieve with this?
I have run lots of surveys previous to this without issue but they were all just one language.
Your dropouts might not be necessarily due to technical reasons, but maybe there are reasons within the sample or the questionnaire itself. Can you see where exactly those dropouts happen?
Reasons I can imagine top of my head that might cause problems with multilingual surveys:
- Approach / language of the questionnaire
- Bad sample quality
- People receive the wrong language as default
In general, we usually try to avoid to run surveys multilingual, but rather have one survey per country/language. Because often you also need to change the structure / questions of the survey a bit, when adapting to different countries, etc.
But of course, multilingual surveys should work. No idea if the size of the session files increases, maybe someone else can help there.
But maybe you can check what the size of these session files currently is, that might be a good indicator already.
Your server specs look pretty good, how is it connected to the internet? What bandwidth does it have?
Help us to help you!
Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
Always provide a LSS file (not LSQ or LSG).
