The previous change enables the `pack.writereverseindex` to see
the effect of writing reverse index in the performance test.

Remove the `pack.writeReverseIndex` configuration.

Below is the result of performance test. Output format is in
seconds.

Tests 4-15 are without the use of lookup table. The rests are
repeatation of the previous tests but using lookup table.
