Image Conversion Time

Post by void »

I am going through a server refresh where I work.

Code: Select all

Server 1:

CPU Number = 4
Physical Memory = 16 GB
Virtual Memory = 25 GB
OS = Solaris 8

Server 2:
CPU Number = 44 (20% faster)
Physical Memory = 256 GB
Virtual Memory = 2 GB
OS = Solaris 10 (Virtual Zone, no restrictions on CPU/Memory usage in this zone.)
ImageMagick Version = 10.0.8

        libpthread.so.1 =>       /usr/lib/libpthread.so.1
        libfreetype.so.6 =>      /usr/local/lib/libfreetype.so.6
        libz.so =>       /usr/lib/libz.so
        libdl.so.1 =>    /usr/lib/libdl.so.1

        /platform/SUNW,Sun-Fire-15000/lib/libmd5_psr.so.1
On server 1, it takes about 10 seconds per image conversion, whereas on server 2, it is taking anywhere from 30 - 60 seconds per image. I am at a loss to explain the difference with this process. Any help or direction on what to check would be most helpful. Any additional information that is needed, please ask and I can provide.

- Thanks in advance.

Server 2 is most likely caching pixels to disk. Add -debug cache to your command line and see if the image conversion takes place in memory or on disk. If you can install/run the latest ImageMagick release, 6.3.7-9.

I have been unable to get the latest version of ImageMagick to compile on Solaris 10. I will look into that version further, but for now, here are the results.
