Final answer:
For a workload that is not IOPS intensive, increasing RAM is typically the most effective solution to improve performance, rather than focusing on disk performance or adding more storage.
Step-by-step explanation:
If your workload isn't IOPS (Input/Output Operations Per Second) intensive, you might not need to focus on disk performance. Instead, you should consider other aspects of your system that could be improved to handle your specific workload more efficiently. Here are the options mentioned:
- Increase RAM: If your system is running out of memory or is frequently using swap space, increasing RAM can help reduce IO wait times and improve overall performance.
- Upgrade CPU: If your workload is CPU-intensive, with tasks that require significant processing power, upgrading to a faster or more efficient CPU might be beneficial.
- Use SSD: The advice to use an SSD would be more applicable if the workload were IOPS intensive, as SSDs provide faster data access speeds than traditional HDDs. However, if this is not the case, an SSD upgrade may not be necessary.
- Add more storage: If running out of space is an issue, adding more storage would help, but it would not necessarily improve performance if the workload isn't storage-intensive.
In conclusion, if the workload isn't IOPS intensive but performance optimizations are still required, increasing RAM is typically the most effective approach to consider.
