Okay, so I added serialization to the types (why did you leave it out?) struct X { int p; double q; private: friend boost::serialization::access; template <typename Ar> void serialize(Ar& ar, unsigned) { ar & BOOST_SERIALIZATION_NVP(p); ar & BOOST_SERIALIZATION_NVP(q); } }; struct Y { float m; double n; private: friend boost::serialization::access; template <typename Ar> void serialize(Ar& … Read more
Use super secret operator (Negative match N) UPD: G2 – is in my example, as I extract two groups from each encounter. each encounter is “uuid” in g1 and g2 is second part I need second part here. that’s why $2$ template and g2. If your encounters in one group you ll most likely use … Read more
There is a possibility to get closer to what browser-perf is doing by collecting the chrome performance logs and analyzing them. To get performance logs, turn on performance logs by tweaking loggingPrefs desired capability: from selenium import webdriver from selenium.webdriver.common.desired_capabilities import DesiredCapabilities caps = DesiredCapabilities.CHROME caps[‘loggingPrefs’] = {‘performance’: ‘ALL’} driver = webdriver.Chrome(desired_capabilities=caps) driver.get(‘https://stackoverflow.com’) logs = … Read more
Socket/Connect and Read/Response timeouts can be set from Http Request Defaults section at jmeter GUI. See sample: Connect timeout: 3 seconds Response timeout: 20 seconds.
The max number of threads is determined by a lot of factors, see this answer https://stackoverflow.com/a/11922239/460802 There is a big difference in what you are proposing. “500 threads, Loop 1 ” Means 500 threads AT THE SAME TIME doing the loop ONCE. “50 threads, loop 10” Means only 50 threads AT THE SAME TIME doing … Read more
Merge sort does fewer compares, but more moves than quick sort. Having to call a function to do the compares increases the overhead for compares, which makes quick sort slower. All those if statements in the example quick sort is also slowing it down. If the compare and swap are done inline, then quick sort … Read more
You can extract the performance data of the UI level of a Web App by accessing Network Panel Data on Google Chrome Developer Tools through Selenium by injecting a JavaScript as follows : Selenium-Java Snippet driver.get(“http://www.google.com”); System.out.println(driver.getTitle()); String scriptToExecute = “var performance = window.performance || window.mozPerformance || window.msPerformance || window.webkitPerformance || {}; var network = … Read more
As per you test case and duration settings, I think, you are making confusion with the Threads and Requests. In short: You must use Ramp-up as 240 seconds for this scenario. Let me describe you in details: Ramp up is the time in which all the users arrive on your tested application server. Requests are … Read more
Let’s take a look at this python function: def py_fun(i,N,step): res=0.0 while i<N: res+=i i+=step return res and use ipython-magic to time it: In [11]: %timeit py_fun(0.0,1.0e5,1.0) 10 loops, best of 3: 25.4 ms per loop The interpreter will be running through the resulting bytecode and interpret it. However, we could cut out the interpreter … Read more
tl;dr doNotOptimizeAway creates an artificial “use”s. A little bit of terminology here: a “def” (“definition”) is a statement, which assigns a value to a variable; a “use” is a statement, which uses the value of a variable to perform some operation. If from the point immediately after a def, all the paths to the program … Read more
