| Hi, I have created some indexes on 5 tables. The performance was faster. After a weeks time the query time was slower and then I rebuild the indexes and then the performance was faster.So How often I need to do the rebuilding the indexes?Thanks,Sandesh |

| We rebuild indexes when the fragmentation is more than some threshold (can't remember what that is offhand, but you can obviously "tune" the threshold that you choose) |
