Thus, our second goal is to increase the cache hit
ratio, and thereby decrease the network traffic caused by data transfer.
This implies that even if we impose a limit that a block request can be forwarded at most four times, the cooperative cache hit
ratio would decline by only 0.
This is because the cost of aborts in this experiment is rather low due to cache hits
that occur when aborted transactions run again.
We adopt three metrics, namely cache hit
rate (HR), average total content delivery latency (ATL) and data traffic volume (DTV) (including local traffic, inter-cloudlet traffic and outbound traffic), which are defined below.
Cache sizes and class cache hit
ratio percents 8k: 18% 16k: 37% 32k: 50% 64k: 54% Note: Table made from line graph.
Figure 5 shows that the cache hit
ratio of our strategy is always higher than IR and UIR strategies.
To minimize the cycle-count overhead of this instruction, we would want to optimize its execution for the common case, which is a data cache hit
modified the annotations around each memory reference to test for a cache hit
before invoking the full cache simulator.
Thus, machines such as this can be considered specialized in the sense that problems with good cache hit
ratios achieve high performance.
AutoCache performs with an amazing cache hit
rate," said DaPrano.
If a prefix with one or more children prefixes is allowed to be cached, the cache hit
result may or may not be the longest matching prefix.
You want to be able to monitor live, production activity at the disk controller and logical unit level for such things as: total I/Os (read and writes), read percentage (percentage of the total I/Os that are reads), cache hit
percentage (percentage of reads found in the cache as opposed to requiring a disk access), current throughput in MB/sec, and current I/O rate per second.
