In PHP does max_execution_time affect shutdown functions that are run through a register_shutdown_function() call?

阅读更多关于 In PHP does max_execution_time affect shutdown functions that are run through a register_shutdown_function() call?

问题 I have a shutdown function registered using register_shutdown_function() that takes a long time to complete. Will PHP's max_execution_time cause PHP to terminate this function or will it run until it completes or errors out? 回答1: It will run to completion. http://us2.php.net/manual/en/function.register-shutdown-function.php#33575 来源： https://stackoverflow.com/questions/4620517/in-php-does-max-execution-time-affect-shutdown-functions-that-are-run-through-a

How can I increase the 6 minute execution limit in Google Apps script?

阅读更多关于 How can I increase the 6 minute execution limit in Google Apps script?

问题 Is there any way to increase the 6 minute execution time limit for Google Apps Scripts? I thought that the answer might be the Early Access program for G Business Suite. I might be willing to pay $10 a month for G Business Suite, if I could get into the Early Access program, in order to increase the execution limit from 6 minutes to 30 minutes. But an Advisor from the G Suite Help Forum said that Early Access is a limited program, which means that there is no guarantee that I could get that.

问题 This question already has answers here : How to subtract microtime and display date with milliseconds in php? (2 answers) Closed last year . public function execution_time($begin = null) { if($begin == null){ return microtime(true); } else { $result = date("H:i:s", microtime(true) - $begin); return $result; } } I'm trying to count the execution time. But the problem is when execution time is lesser then 1 hour, it writes wrong timestamp, for example: $timeBegin = execution_time(); sleep(8);

How do I reduce execution time and number of cycles for a factorial loop? And/or code-size?

阅读更多关于 How do I reduce execution time and number of cycles for a factorial loop? And/or code-size?

问题 Basically I'm having a hard time getting the execution time any lower than it is, as well as reducing the amount of clock cycles and memory size. Does anyone have any idea on how I can do this? The code works fine I just want to change it a bit. Wrote a working code, but don't want to mess up the code, but also don't know what changes to make. ; Calculation of a factorial value using a simple loop ; set up the exception addresses THUMB AREA RESET, CODE, READONLY EXPORT __Vectors EXPORT Reset

问题 I'm on a shared hosting platform and would like to throttle the queries in my app so that if the total execution time exceeds a certain amount over a variable time period then I can make the app cool off and then resume later on. To do this I would like to find out how long each of my queries take in real time and manage it within the app and not by profiling it externally. I've seen examples in PHP where the time is recorded before and after the query (even phpMyAdmin does this), but this

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)]))) print("%d lines generated" % len(global_tab)) And the result with linux time command: $ time python3 DEV

Problem with function session_start() (works slowly)

阅读更多关于 Problem with function session_start() (works slowly)

问题 I have a problem wtih session_start() on primary server. When I load page for the first time, it takes less than 1 second to complete request. If I'll wait for approximately 12-15 seconds and then reload page, time of loading will be the same. But when I'm trying to refresh page after, for example, 3 or 5 seconds after initial loading, time of the server's response equals 10 seconds. I made some tests to define a bottleneck in my script and I found out, that function session_start() executes

So the question is: how would I go
