Hi Everyone, GCC135 is a Power9 machine. Benchmarking on the machine shows performance is off. For example, here are some numbers for AES in ECB mode:
GCC112 (Linux, ppc64le, 3.7 GHz, GCC 8.2): * 1.12 cpb, 2851 MB/s GCC119 (AIX, ppc64be, 4.1 GHz, GCC 8.2): * 0.54 cpb, 7242 MB/s GCC135 (Linux, ppc64le, 3.8 GHz, GCC 8.3): * 1.94 cpb, 1815 MB/s All algorithms show a similar slowdown. SHA is so slow I am considering disabling in-core crypto for SHA and going back to the integer unit. What is different about GCC135? Is the Power9 hardware really that slow?
