MODS.DB9.DK

[Blisk]

This mod slows down forum very much.
I think because everytime I load index page this mod check all users for birthday. I think that is the problem.
Maybe it will be better that this mod do that only few times per day.
Or maybe some other improvement to speed up page loading where this mod is installed.

[Niels]

you are rigth about the speed on index page, it will slow it down - any extra information needed will slow down your www.

Sadly windows OS can't handle dates back in time (prior to 1986), and as you might now, meny users have a birthday back in time
therefore it have been nessesary to make php functions witch can calculate dates prior to this, as the dates have to be calculated for all users, this will take some time, all depending on how meny users have filled a birthday.

if your server is runing on a NIX server (linux), you may gain speed improvements if installing this mod as described for unix, see the how-to about how to do this (you need to modify functions.php)

tnx for info, I use linux server.
I will check, that what you suggest.

Sorry I don't understand quite good what I must change, can somebody help me???
I change
//function realdate($date_syntax="Ymd",$date=0)
with
//{ return create_date($date_syntax,$date*86400+1,0); }
Bit doesn't work!

[Niels]

it is the COMPLETE function witch should be replaced... (ONLY FOR SERVERS RUNING *NIX e.g. linux)

e.g.

FIND

Code: Select all

function realdate($date_syntax="Ymd",$date=0)
{
   global $lang;
   $i=2;
   if ($date>=0)
   {
       return create_date($date_syntax,$date*86400+1,0);
   } else
   {
      $year= -(date%1461);
      $days = $date + $year*1461;
      while ($days<0)
      {
         $year--;
         $days+=365;
         if ($i++==3)
         {
            $i=0;
            $days++;
         }
      }
   }
   $leap_year = ($i==0) ? TRUE : FALSE;
   $months_array = ($i==0) ?
      array (0,31,60,91,121,152,182,213,244,274,305,335,366) :
      array (0,31,59,90,120,151,181,212,243,273,304,334,365);
   for ($month=1;$month<12;$month++)
   {
      if ($days<$months_array[$month]) break;
   }

   $day=$days-$months_array[$month-1]+1;
   //you may gain speed performance by remove som of the below entry's if they are not needed/used
   return strtr ($date_syntax, array(
      'd' => ($day>9) ? $day : '0'.$day,
      'D' => $lang['day_short'][($date-3)%7],
      'F' => $lang['month_long'][$month-1],
      'j' => $day,
      'l' => $lang['day_long'][($date-3)%7],
      'L' => $leap_year,
      'm' => ($month>9) ? $month : '0'.$month,
      'M' => $lang['month_short'][$month-1],
      'n' => $month,
      't' => $months_array[$month]-$months_array[$month-1],
      'y' => ($year>29) ? $year-30 : $year+70,
      'Y' => $year+1970,
      'z' => $days,
      'a' => '',
      'A' => '',
      '\\d' => 'd',
      'd' => ($day>9) ? $day : '0'.$day,
      '\\D' => 'D',
      'D' => $lang['day_short'][($date-3)%7],
      '\\F' => 'F',
      'F' => $lang['month_long'][$month-1],
      'g' => '',
      'G' => '',
      'H' => '',
      'h' => '',
      'i' => '',
      'I' => '',
      '\\j' => 'j',
      'j' => $day,
      '\\l' => 'l',
      'l' => $lang['day_long'][($date-3)%7],
      '\\L' => 'L',
      'L' => $leap_year,
      '\\m' => 'm',
      'm' => ($month>9) ? $month : '0'.$month,
      '\\M' => 'M',
      'M' => $lang['month_short'][$month-1],
      '\\n' => 'n',
      'n' => $month,
      'O' => '',
      's' => '',
      'S' => '',
      '\\t' => 't',
      't' => $months_array[$month]-$months_array[$month-1],
      'w' => '',
      '\\y' => 'y',
      'y' => ($year>29) ? $year-30 : $year+70,
      '\\Y' => 'Y',
      'Y' => $year+1970,
      '\\z' => 'z',
      'z' => $days,
      '\\W' => '',
      'W' => '') );
}

REPLACE WITH

Code: Select all

function realdate($date_syntax="Ymd",$date=0)
{ return create_date($date_syntax,$date*86400+1,0); }

this should dramatically improve the speed on index.

you see the complex code is needed if your server is windoze, while unix will settel with the small version - this code is executed for every user on your site, so it should improve your speed...

btw. I use the windoze version

[Blisk]

TNX for help!
I must trully say, that I like to use windoze too, because with linux there is so much trouble, but now I learn a lot, and to install a linux and forum on in is really simple.
But all other things makes life complicated, windows are much simplier.

[Niels]

Once a linux is up and runing, and you have done the configuration, it will will run for ever, without need of "maintaince" - whitch can not be said about a windoze.
once you get microsoft inside a machine,, you need constantly to monitor it, clean up, update it, restart, re-install, ect.
I belive in long term, it is a benefit to run on linux.

As a developper, it is better to run on a windoze - mainly becouse it is not as compatible as linux.
in php ther eis a few limitations regarding windoze + PHP
some features will simply not work on a windoze server.
you see I make software, witch should work on both windoze and linux - If I was runing on a linux, I could not detect, and test the fault, witch only showed on a windoze.
So I guess Im kind of stuck with windows...
I do though belive that I the futare are changing to linux, this will though require me to have "windoze "development" mashine runing to test on

[Niels]

need of more speed ?
I have now made a data cache, with caches the birthday list, so this is only calculated for every 10 min.
this will bring your index backto the "old" speed - atleast the majority of the time.
