The Baal Shem Tov zt'l said that the galus is so long because people rush through the brachah of עולם אהבת. If we spent more time on this brachah and recited it with more devotion and concentration, the galus would end. Some shuls follow this counsel every day, and עולם אהבת can take them five minutes, and many batei midrashim say עולם אהבת in this manner on Shavuos.
In the beis medresh of Rebbe Naftali of Ropshitz zt'l, the brachah ahavas olam took hours and was said with much hislahavus. One year, a student of the Chasam Sofer's zt'l yeshiva was in Ropshitz for Shavuos. When he returned to the yeshiva, the Chasam Sofer asked him what he saw in Ropshitz. The student described the magnificent way they said ahavah rabba. The Chasam Sofer was very impressed and praised the Ropshitzer chassidim for praying like that.
