This was done on 3-28-2012. Pretty much all the ROMs have had new releases since then. So these benchmarks do not accurately reflect the current performance of the ROMs.
Full wipe procedure done before each flash.
Coldboot done for each ROM before running Quadrant. Not doing coldboot resulted in lower I/O score in some cases.
Testing was done using the default settings and kernel of the ROM. No kernels were flashed separately.
Overclock was tested only if the ROM and its default kernel supported it, using the maximum frequency allowed in the ROM's settings + force GPU rendering set to enable in developer settings.
