Your database may have the same size but more blocks are used.

Depends on a lot of factors.
CPU, I/O and your rman settings.
RMAN 11g compression algorithm is very different (better) than previous versions.

Perhaps you need to tune the backup, check out the "Tuning RMAN Performance" chapter in the fine Oracle® Database Backup and Recovery User's Guide.
