Why are PreProd Sites Slower than Production Sites?

PreProd sites may be slightly slower than productions sites for two reasons:

1.      PreProd sites are not run from priority servers. Priority servers are reserved for production sites, to ensure the highest level of stability and performance for live LearnFlex sites. Priority servers are built with the best available hardware.

2.      PreProd servers have a language library that must be loaded when the site is first loaded. Loading this library may result in a minor loading time. The language library is cleared from the servers RAM every 20 minutes to reduce latency (increase performance) in other parts of the system.
