How can I measure the performance of my cache system?

You can measure cache performance by analyzing hit rates, miss rates, and latency. Would you like to know how to calculate these?

Yes, please explain how to calculate hit and miss rates.

Hit rate is calculated as the number of cache hits divided by the total number of cache accesses. Miss rate is the opposite. Do you need examples?

That would be helpful. Can you provide a sample calculation?

Sure! If you have 80 cache hits and 20 misses, your hit rate is 80/(80+20) = 0.8 or 80%. Miss rate is 20/(80+20) = 0.2 or 20%. Does that make sense?

Yes, it does! What about measuring latency?

Latency can be measured by recording the time taken to retrieve data from the cache. You can average this over multiple requests for accuracy.
