Memory benchmarking

In this recipe, we will be discussing how to benchmark the memory speed using open source tools.

Getting ready

As with the CPU test suite, phoronix supports one another memory test suite, which covers RAM benchmarking. Otherwise, we can also use a dedicated memtest86 benchmarking tool, which performs memory benchmarking during a server bootup phase. Another neat trick would be to create a tmpfs mount point in the RAM and then create a tablespace on it in PostgreSQL. Once we create the tablespace, we can then create in-memory tables, where we can benchmark the table read/write operations. We can also use the dd command to measure the memory read/write operations.

How to do it...

Let us discuss how to install phoronix and how to ...
