Performance problems due to sequential read on tables WBCROSSGT and CROSS

Hello all,

got the SAPNW2004s Sneak Preview ABAP installed. Performance is quite ok. But with certain dictionary operations like creating new attributes for a class I experience exceptional long runtimes and timeout dumps. In SM50 I see a sequential read on table WBCROSSGT. In OSS I can't find anything applicable yet for this release (SAP_BASIS 700, support level 5).

Any suggestions appreciated.
