execution-time

问题 Can I measure the code size with the help of an fseek() function and store it to a shell variable? Is it possible to extract the code size, compilation time and execution time using milepost gcc or a GNU Profiler tool ? If yes, how to store them into shell variables? Since my aim is to find the best set of optimization technique upon the basis of the compilation time, execution time and code size, I will be expecting some function that can return these parameters.

问题 Void-pointer, variant-objects and any-objects are amazing because they can store many different types in the same variable. But I have a problem with them, I need to specify their type (creating and/or de-referencing them) in the execution time, is it possible? To be more clear, for example, as far I know, to create and de-reference them I have to do this: void* ptr = new int(8); variant<int, float> var = 8; any a = 8; ... cout << *(int*)ptr; cout << get<int>(var); cout << any_cast<int>(a);

问题 I'm using LDBC dataset to test execution time in Neo4j 4.0.1, SF = 1, and I use java to connect Neo4j, ResultSummary.resultAvailableAfter() to get the execution time, which is the time to get the result and start streaming. But for the same query, when I run for the first time, the execution time seems reasonable, like hundreds of ms, but when I continue running this same query, the execution time becomes almost 0. I guess it's effect of query cache, but is there any proper approach to test

问题 I'm fairly new to Python, and I'm trying to write some huge lists (with random letters inside). Actually it takes me around 75 - 80 seconds on my machine for 2,000,000 lines. import timeit import random, string global_tab = [] global_nb_loop = 2000000 print("Generate %d lines" % global_nb_loop) global_tab = [] for x in range(global_nb_loop): global_tab.append(("".join( [random.choice(string.ascii_letters) for i in range(15)] ), "".join( [random.choice(string.digits) for i in range(2)])))

问题 I would like to change the maximum execution time for a PHP script. In the script I have tried ini_set("max_execution_time", "1000"); and set_time_limit(1000); together and separately. I also added this line to .htaccess: php_value max_execution_time 1000 php.ini has safemode off and the Apache server has the flag AllowOverride All . What must I do to get the server to allow a longer execution time? 回答1: Setting the variable in the ini file works for me: max_execution_time = 1000; set_time
