We have recently upgraded from tamino V4.4.1 to V8.0.1.
When we were developing the system in with V4.4.1 we spent quite a lot of time tuning our queries to be as fast as possible.
Now having moved to V8.0.1 we have noticed that some of them run slower than on V4.4.1. This could be a large amount of work for us to go through and tune the queries again.
Has anyone else noticed this ?
Is this a known problem ?
Have the criteria for tuning queries changed ?
I check the documentation but it looked like the section on tuning queries had not changed since V4.4.1.
