Help me to configure ImageMagick

[dev.alex89]

I need to configure imagemagick so as to obtain the highest possible speed of processing photos, I read one article which said that it will help.
After this stopped working formats as PNG, JPG, etc.
ImageMagick-6.7.1-4

Code: Select all

convert logo: logo.png
convert logo: logo.jpg

As a result, have created images in a GIF format

I have installed, configured like this:

Code: Select all

sudo apt-get --purge remove imagemagick 
tar xvfz ImageMagick.tar.gz
cd ImageMagick-6.7.1
./configure --disable-openmp --with-quantum-depth=8 --disable-largefile
make
sudo make install

How to fix? And what else do the settings to speed up ImageMagick
