Sammanfattning
The overall performance of a computer system that reads a lot of data is directly
linked to its ability to extract performance from the storage hardware. This thesis,
conducted together with the company Carmenta, examines how to optimize a system’s
data reads. The targeted storage device is an NVMe SSD. Several experiments
simulating different workloads were conducted and laid the foundation for a new set
of guidelines. Lastly, the guidelines were evaluated in a custom-built benchmark.
Based on the evaluation, it was concluded that by using the guidelines, a system’s
performance could be increased.
