It's clear that G++ 4.3.2 performs better on a smaller data set, while
intel outperforms g++ on random read test by 36.76 seconds.
The test was run in a single node local fs environment.
Machine spec:
4GB non ECC RAM,
Extended brand string: "Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz"
single SATA II disk was used during the test (no RAID)
