After upgrading Essbase from the 11.1.1.x to 11.1.2.x releases, run through your sanity tests, such as outline dimension build updates, data loads, calculations, queries, etc. If you encounter any performance issues on the newer release of Essbase (for either ASO or BSO models) as compared to the previous release, rebuild the problematic outline on the current 11.1.2.x release. It is possibly that the outline did not migrate properly during the upgrade process.
Once you have rebuilt the outline, run through your tests again and if you still encounter performance issues, open an SR with Support.
