What factors impact the performance of cache?
There are many factors that can affect cache performance, such as cache size, cache block size, association and replacement algorithm
Why not make cache larger?
A cache is intended to speed things up. The larger the cache, the slower it performs. If it becomes slower to access the cache than the memory itself, it defeats the purpose of having a cache.
Is buffered-cache most efficient?
Write-back cache is the most efficient when performance is paramount.
Cache memory does not affect the performance of the CPU?
true
If the hard drive is replaced with a larger unit, will it make the cpu faster?
A larger hard drive will increase the overall speed and performance of your computer.
What cache typically has the most memory?
Caches are generally defined as L1, L2, and L3. If a CPU has any cache memory at all, it will have at least L1 cache. L1 cache is the fastest, and most expensive, type of cache memory. Usually CPUs will only have a very small amount of L1. L2 is typically larger, less expensive, and slower than L1. L3 is less expensive, larger, and slower than L1 or L2, if present. All three levels of cache memory are magnitudes faster than system memory. Systems withequivalenthardware, including CPUs will identical speeds, will perform better at certain tasks when more cache memory is present, with L1 cache adding the most performance boost.
Why does the speed of a computer increase as soon as we increase the size of the cache memory?
Basically for the same reason that cache itself helps increase the speed. If there is more cache memory, the computer will have more information readily available, and there will be less cases where the information CAN'T be found in cache, and the CPU needs to access actual RAM, which is slower (or whatever other source of data the cache is supposed to speed up).
Is level 3 cache faster for the CPU to reach and is larger in size than Level 1 cache?
False
How good is 2MB L2 cache as compared to 3MB L2 cache?
Larger the size is better but it is hard to know how much better. Read/Write latency (time) is also an important factor for performance.
Why do systems not use more or large cache memory if they are so useful?
cache is more expensive and it will increase the cost of the system terribly. processing of more than one cache will complicate the design of CPU and increase the burden on CPU.
What to do to not damge your cache memory for RuneScape?
"Damaging" the RuneScape cache on your computer does nothing. I frequently delete it to refresh the data which in turns boosts performance.
What is the difference between cache-memory and primary-memory?
Cache memory is smaller and quicker, primary memory larger and slower.
