Convert from dpx to tiff, slow on nfs mount

Post by hansj »

Hi,

The following command takes a long time (~13-19 seconds) to execute on an nfs mount:

Code: Select all

convert -debug all inputimage.dpx -depth 16 outputimage.tif
Running the same command on a local file system is fine (~0.5 seconds)

I'm on Centos 5.3, 64 bits and I've downloaded the ImageMagick-6.6.0-8 and configured and installed with the following options:

Code: Select all

./configure --without-perl --disable-openmp --program-suffix=-6.6 --prefix=/net/sw/opt/ImageMagick-6.6.0-8/ --disable-installed
I've tried to compile with and without threading and openmp

The same symptoms are shown in the 6.3.8 version in the default CentOS 5.3 repo.

Anybody know what could be going on here?

Debug output further down.

Thanks!

Edit: Changed timing information, as it's varying..
Edit2: This only happens on tiffs, other formats like jpeg or png seems fine.
