benchmarking

To what extent does Google Analytics impact performance? I'm looking for the following: Benchmarks (including response times/pageload times et al) Links or results to similar benchmarks One (possible) method of testing Google Analytics (GA) on your site: Serve ga.js (the Google Analytics JavaScript file) from your own server. Update from Google Daily (test 1) and Weekly (test 2). I would be interested to see how this reduces the communication between the client webserver and the GA server. Has anyone conducted any of these tests? If so, can you provide your results? If not, does anyone have a

There are two ways to zero out an integer/float array: memset(array, 0, sizeof(int)*arraysize); or: for (int i=0; i <arraysize; ++i) array[i]=0; obviously, memset is faster for large arraysize . However, at what point is the overhead of memset actually larger than the overhead of the for loop? For example, for an array of size 5 - which would be best? The first, the 2nd, or maybe even the un-rolled version: array[0] = 0; array[1] = 0; array[2] = 0; array[3] = 0; array[4] = 0; Michael Burr In all likelihood, memset() will be inlined by your compiler (most compilers treat it as an 'intrinsic',

I created a simple class to benchmark some methods of mine. But is it accurate? I am kind of new to benchmarking, timing, et cetera, so thought I could ask for some feedback here. Also, if it is good, maybe somebody else can make use of it as well :) public static class Benchmark { public static IEnumerable<long> This(Action subject) { var watch = new Stopwatch(); while (true) { watch.Reset(); watch.Start(); subject(); watch.Stop(); yield return watch.ElapsedTicks; } } } You can use it like this: var avg = Benchmark.This(() => SomeMethod()).Take(500).Average(); Any feedback? Does it look to be

I'm currently using GCC, but I discovered Clang recently and I'm pondering switching. There is one deciding factor though - quality (speed, memory footprint, reliability) of binaries it produces - if gcc -O3 can produce a binary that runs 1% faster or takes 1% less memory, it's a deal-breaker. Clang boasts better compile speeds and lower compile-time memory footprint than GCC, but I'm really interested in benchmarks/comparisons of resulting compiled software - could you point me to some or describe your experiences? Here are some up-to-date albeit narrow findings of mine with GCC 4.7.2 and

I am using the library Crypto++ 5.6.5 and Visual Studio 2017. How can I calculate the encryption time for AES-CCM? I would like to know how to calculate the encryption time for AES-CCM. The Crypto++ wiki provides an article Benchmarks . It provides a lot of details regarding library performance, how throughput is calculated, and it even references the source code where the actual throughput is measured. Believe it or not, a simple call to clock works just fine to measure bulk encryption. Also see Benchmarks | Timing Loop in the same wiki article. To benchmark AES/CCM, do something like the

I have a lot of (about 1 million in second)structural data that must be insert to database I see a lot of benchmark about sql vs noSql and type of Nosql then collect cassandra as database but I create a benchmark to test mysql vs cassandra in write/update/select speed mysql have better performance in my benchmark, I want to know what is my mistake?? php use as programming language YACassandraPDO and cataloniaframework use as php driver and PDO use as mysql driver my server is centOS 6.5 with 2 core CPU and 2GB RAM, mysql and cassandra have default configuration detail of benchmark: cassandra
