I have a HP Compaq dc7700p Convertible with Intel Core Duo
CPU - 6400
2.13Ghz. 1.98Gb ram.
I am running convert from the command line for a simple
"convert $file.jpg
$file.png" sequence on many hundreds of files.
The files are a varied selection of RGB JPGs, filesizes from
58k to 11Mb.
At unpredictable intervals, and on different files, convert
hangs. When it
does so, it can hang for anything from a few seconds to a
couple of minutes.
An example: 100_1455.jpg is 11Mb.
Convert 100_1455.jpg 100_1455.png takes only about 2 seconds
to run
normally.
I can repeat the command line many times and obtain the same
2 second
runtime, but then at no predictable interval the process
will hang and take
60-90 seconds.
I have run a test pattern repeatedly using the same 20
images in a batch
file, measuring the processing time and recording the
results and can
establish no pattern related to filesize.
I have modified/restore some system optimisation settings
but with no
differing result.
My only conclusion is that convert is having a problem with
this processor.
Can anybody point me to a resolution?
Mike
