some pages are very slow when not defaultlanguage

Question

When I request a page in another language the serverresponse is very slow. In the defaultLanguage it is fast.

www.domain.com --> is fast
www.domain.com/?L=1 --> is slow
www.domain.com/?L=2 --> is slow

Only Pages that have multilanguage (singletree) configured are slow. But the content is an 1:1 copy of the defaultLanguage for now. And also only the pages that have the tx_news plugin listview are slow.

How can I debug this? What could cause that?

Answer 1

See rob-ot comment.

The querys run very slow when there are translations. As workaround I use different folders for each language and set the startingpoint with typoscript when an alternative language is called.
