especially for sp, is this related to if the parameters are set vs passed in?

actions on upgrade
- set db to compatiblity-level 90 (sql2005)
- reindex
- update statistics

And there could be other things when new 2K5 instance
- other configuration of memory/disks/tempdb
- full recovery model and not yet a transactionlog backup running

it is already on 90.

glad you mentioned something about the backups.. it is goofy.. we are automatically taking tlb but not full backups.. but i put on simple .. (we were able to afford that) that did not fix it either..

i ran sp_updatestats  and that has fixed it..

so what is the lesson? after every restore, run sp_updatestats? is it only when you are going up a version or even within same version?
