BW_MEM_RD(8) LMBENCH BW_MEM_RD(8)NAMEbw_mem_rd - time memory read rate (with overhead)
SYNOPSISbw_mem_rd size
DESCRIPTIONbw_mem_rd allocates the specified amount of memory, zeros it, and then
times the reading of that memory as a series of integer loads and adds.
Each four byte integer is loaded and added to accumulator.
The size specification may end with ``k'' or ``m'' to mean kilobytes (*
1024) or megabytes (* 1024 * 1024).
OUTPUT
Output format is "%0.2f %.2f\n", megabytes, megabytes_per_second, i.e.,
8.00 25.33
MEMORY UTILIZATION
This benchmark should move approximately the reported amount of memory.
