Hi All,
I am a fio newbie. I am writing benchmarks to test the performance
improvement with my work.
I want to create the following standard scenario:
- 90% writes go to 10% of the files (HOT Files)
- 10% writes go to 90% of the files (Cooler files)
How do I go about doing this? I looked at the zipf distribution and
played with theta a bit. However, I can never specify how many times a
particular file must be accessed at max - to be able to control this
percentage.
How can we achieve the above scenario?
I appreciate your feedback a lot! Thanks!
Best Regards,
Surbhi
