Bob,
I know you're looking for single or dual core results, but I thought I'd
give you some results in case you don't get responses from others.
It takes about a second to convert the image.
Running:
ImageMagic 6.2.8
8 @ 2.13GHz Xeon E5506 CPU's (2 quad cores)
768 MB Ram / 395 MB free
CENTOS 5.4 i686 virtuozzo.
My average load before and after running the conversion is about .06, during
conversion it spiked to ~.44
Also, are you sure HG is only giving you a single CPU? (you can tell from
"Server Status >> Server Information" in WHM) For the prices that they
advertize they really should be giving you more than one core.
HTH,
Rob

Subject: [thelist] What is normal 'ImageMagick' processing on VPS hosting?
I'm twisting this thread a tad, so new Subject. I uploaded a sample,
typical, 1.5MB jpg to my website. If you are curious and are willing to
help, assuming you have ImageMagick (the 'convert' command) installed
please do the following test. The results will help confirm whether this
is server/hardware problem, ImageMagick problem or that the slowness is
normal for a single core VPS installation:
1) Download the test image from
www.dottedi.biz/images/diagnostics/cat1500kb.jpg
2) Upload to your Linux VPS server
3a) Assuming you have shell/SSH access , log into your server and
execute the following commands from a command prompt from the same
folder as the image:
date
convert cat1500kb.jpg -thumbnail '100x100>' -background white
-gravity center -extent 100x100 100px.jpg
date
convert cat1500kb.jpg -resize 480x480 480px.jpg
date
convert -version
3b) If you don't have shell access, upload the following php script to
the same web accessible folder as the image and visit the page:
<?php
echo "hh-mm-ss<br />";
echo "<br />";
$date = date("H-i-s");
system("convert cat1500kb.jpg -thumbnail '100x100>' -background
white -gravity center -extent 100x100 100px.jpg");
echo "$date<br />";
$date = date("H-i-s");
echo "$date<br />";
echo "Thumbnail completed<br />";
echo "<br />";
system("convert cat1500kb.jpg -resize 480x480 480px.jpg");
echo "$date<br />";
$date = date("H-i-s");
echo "$date<br />";
echo "Simple resize completed completed<br />";
echo "<br />";
system("convert -version");
?>
4) Note your webserver hardware configuration:
CPU 1.98GHZ
RAM: 1344MB
Core: Single (preferred, or Dual)
5) Note how long it takes each to process.
I know this is asking a lot.
Thx, Bob
