I noticed that using an NSDateFormatter can be quite costly. I figured out that allocating and initializing the object already consumes a lot of time.
I find Google\'s micro benchmark project Caliper very interesting but the documentation is still (except some examples) quite non-existent.
I know that length(x) returns max(size(x)) and numel(x) returns the total number of elements of x, but which is better for a 1 by n array? Does it matter, or are they interchangeable in this case?
I\'ve heard this term used, but I\'m not entirely sure 开发者_如何学JAVAwhat it means, so: What DOES it mean and what DOESN\'T it mean?
F开发者_JS百科irst of all, this is not about the usefulness of microbenchmarks. I\'m well aware of their purpose: Indicating performance characteristics and comparison in a very specific case to highl
I am looking for ways to perform micro-benchmarks on multi-core processors. Context: At about the same time desktop processors introduced out-of-order execution that made performance hard to predict
I\'m running a benchmarking experiment making HTTP calls using JMH. However, there are couple of things that are not clear to me because the JMH Javadoc are like "here I document the annotation n
