Raspberry Pi 2 model B.

[RV]

Zdravim,

nevim kdo co podnikal s RPI2, ale ted v pauzach v praci ho tu trapim 
programem AB (Apache Bench) co ustoji. Nainstalovane PHP 5.4 a Apache 
2.2 plus bezne moduly a GD2 - bezi k tomu SSH, Samba. Apache v defaultni 
konfiguraci.

Napsal jsem jednoduchej skriptik, kterej naplni dvesteprvkove pole 
jednorozmernymi poli o trech prvcich v cyklu a vygeneruje hodnoty pro 
graf, ktery je vykreslen na html strance jako PNG o rozmerech 1200x300:

<?php
require 'phplot/phplot.php';
$plot = new PHPlot(1200,300);

for ($i = 0; $i < 200; $i++)
   {
     $data[$i][0]='';
     $data[$i][1]=$i;
     $data[$i][2]=rand(0, 1000)/100;
   }
$plot->SetDataValues($data);
$plot->SetDataType('data-data');
$plot->DrawGraph();
?>
**********************************************************
z nize uvedeneho vyplyva, ze to cele zcela jiste uvazne na te proklate 
100Mb sitovce. I tak ukocirovat 100 paralelnich useru pri odbavovani 
1100 pozadavku za sekundu, je na zarizeni, ktere je skoro studene a 
basti 2.5W je skvele. Zkusim kde se to zlame pri kolika konkurencncich 
usrech.
