Data
All servers are loaded with the same terminology datasets before benchmarking begins. Using a shared, versioned dataset ensures that differences in results reflect server performance, not differences in loaded content.
The datasets below require separate downloads due to licensing. Some require registration or an active license agreement before access is granted.
