Performance threshold

A non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause a processor of a computing device to:

• determine storage access parameters for a particular hardware configuration and a particular software configuration by running a plurality of benchmarks;
• determine a benchmark matrix based on the plurality of benchmarks;
• determine a threshold performance for the particular hardware configuration and the particular software configuration based on the benchmark matrix;
• intercept system calls at a shim library to analyze a type of the system calls;
• and
• alter the system calls of the particular hardware configuration and the particular software configuration based on the threshold performance and the type of system calls, wherein altering the system calls includes altering a quantity of threads for the system calls.

A system, comprising:

• a processor;
• and
• a non-transitory computer readable medium storing instructions to cause the processor to:
• run a plurality of benchmarks for a combination of a hardware configuration and a software configuration;
• determine a benchmark matrix based on the plurality of benchmarks, wherein the benchmark matrix includes an array of values that represent a performance of the software configuration executing on the hardware configuration;
• determine an input/output (I/O) bandwidth ceiling for the combination of the hardware configuration and the software configuration based on the benchmark matrix;
• determine a performance threshold of an I/O access parameter for the combination of the hardware configuration and the software configuration based on the bandwidth ceiling;
• intercept system calls at a shim library to analyze a type of the system calls;
• and
• alter the system calls of the combination of the hardware configuration and the software configuration based on a comparison between the determined threshold performance and a threshold value and based on the type of system calls, wherein altering the system calls includes altering a quantity of threads for the system calls.
