Replied to Why Laravel 8 Is Burning So High Memory In Each Request?

Replied to Why Laravel 8 Is Burning So High Memory In Each Request?

Thank you for response. I dont use any debugger I do you guess this high memory usage is because of enabling debugger in test mode?

Thank you for response. I am not loading any data I just use memory_get_usage() and it returns about 13 MB I guess that is a lot assuming many users request at the same moment. What happens If we run out of memory just because of framework bootstraping?

Thank you for response but please pay attention that I am not loading any data. I put memory_get_usage() at begining of action and nothing else but it returns 13 MB aproximately. That is very high

I have noticed that if I use PHP memory_get_usage() function in begining of an empty action of controller on my localhost, it returns about 13 MB memory usage. Is not this really a problem? For example if I have a host with 1 GB of ram, how many can use my application simultanously?

Replied to Why Reading File Chunks Takes Lots Of Memory?

Thank u I will check it. Do you see any flaw in my script?

Started a new Conversation Why Reading File Chunks Takes Lots Of Memory?

Hi please somebody helps me. I am trying to read file.txt file in chunks and render to browser. File size is 4.8 MB. When I comment header function calls to just read the file in chunks (500 KB each time) peak memory usage is 1426176 bytes (1.4 MB) which I consider to be high. But worse when I uncomment header function calls, peak memory usage goes up to 15104112 (15.1 MB). What is wrong with my script using such high memory?

<?php
$file='file.txt';   
header('Content-Type: '.mime_content_type($file));
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Length: '.filesize($file));
header('Content-Transfer-Encoding: binary'); 
$handler=fopen($file, 'rb');
$position=0;
$length=1024 * 500;
$filesize=filesize($file);
while(!feof($handler) & $length > 0){
 echo fread($handler, $length);
 $position+=$length;
 $r=$filesize - $position;
 $length = $r >= $length ? $length : $r;
 fseek($handler, $position);
}
fclose($handler);
$h=fopen('x.txt', 'w');
fwrite($h, memory_get_peak_usage());
fclose($h);
