According to a benchmark posted on CLucene's SourceForge wiki, CLucene outperforms Java Lucene by a factor of 2 to 3 during indexing, but search performance is only about 10% better.

The data Michael linked to is quite old and incomplete. The answer is yes mainly because C++ has no GC threads and memory allocations are made in C++ by hand. Even reference counting in C++ will be performed faster in C++ since its compiled to machine code, unlike Java which runs on a VM.
