[OmniOS-discuss] ARC or memory perfomance benchmarks

[Ergi Thanasko]

We are building a new box with Skylake CPU 3.6Ghz and ddr4 rdim 2666Mhz. Been using iozone for multithreaded random IO zpool testing and getting some awesome speed test. What I really want to test it the ram speed. Supermicro gave me some benchmarks for ram at around 200GB/sec sustained bandwidth for 768G of ram. I want to see how it compares with my other DDR3 boxes. I am having trouble finding utilities that will test the ram speed on Solaris, OmniOS or Opendianna. Any help is appreciated

The classic RAM speed benchmark is the 'stream' benchmark, which you
can obtain from https://www.cs.virginia.edu/stream/

Thnx Bob,
That is what SM used on Redhat 7.3, anyone has compiled version around that feels like sharing.
