Crucial PC3200 Memory Review - Linux Tests - STREAM
(Page 8 of 10 )
STREAM
STREAM is a benchmark created by a university researcher to take a look at memory performance trends over time. It is a really small program, as it is composed of two C files. I preferred the Linux test to the Windows test because I was originally going to use PSBench 7 here. However, I was having difficulty getting reproducible results from PSBench 7, and this seemed like an adequate replacement.
I compiled STREAM from source with the options suggested using GCC. Since I'm using the same binary executable for the different kinds of memory, the compiler optimizations do not have an effect on the results.
While the Crucial RAM and the Infineon are almost neck and neck for the Scale and Copy, the dual channel Infineon memory pulls a commanding lead in the Triad and Add tests. I don't think these results are in error since there is a marked jump in the results from the single stick of Infineon RAM in the Triad and Add tests too.
OpenSSL
OpenSSL is a secure sockets layer for Linux, and handles many different encryption algorithms, such as DES, RSA, and Blowfish, as well as hashing functions like MD5 and SHA1. Encryption and hashing are quickly becoming important in the electronic world, so these tests are relevant, but admittedly they are more processor dependent than memory. OpenSSL comes built in with a test to determine how well it performs. I'll be using the DES, Blowfish, and MD5 results for 8KB block sizes.
Here we see the closest set of results yet, and the Crucial memory wins two out of three.
