One of our readers wanted to know how to check our own computer’s L1 and L2 cache memory size and speed, if same is the case with you then here are the details.
Caches are the small and fast memory space that stores the frequently used data so that the time consumed in accessing them is least and thereby the computer performs faster. There is not much of a difference in the L1 and L2 cache just that the former is implemented in the SRAM and the latter in DRAM.
With the use of the tool called Cachchk you can easily check your system’s L1 and L2 cache memory for size and speed. The tool performs memory access timing tests, to see if you have a cache, how many caches, and to check the access speed. Cachchk will also perform memory accesses to verify the L1 and L2 cache usage, it will report the speeds and sizes of each cache, and it will verify if all of your memory is, or is not cached.
