Question: 33
(Choose 1 answer)
Critically evaluate the effectiveness of caching and read-ahead techniques in file-system performance
enhancement, highlighting their respective contributions and potential limitations.
A. Caching significantly speeds up file retrieval but may suffer from cache coherence issues, while read-ahead
enhances performance by predicting file accesses but may cause unnecessary disk reads.
B. Caching and read-ahead techniques have no impact on file-system performance, as their benefits are
negligible compared to other optimization methods.
C. Caching improves disk usage by storing frequently accessed data but leads to increased latency, whereas
read-ahead ensures faster file retrieval without any drawbacks.
D. Caching and read-ahead both substantially improve file-system performance without any associated
limitations or drawbacks.
