    Why is Photoshop CS6 so slow?

    funn1bunn1 Level 1

      I have allocated 60-70% ram to Photoshop already, but when working with a 24mb tif file, Photoshop is slow.

      When working with smaller (ex. 18mb) tif file, Photoshop runs fine.


      In the Activity Monitor, the CPU usage of Photoshop rarely hits 100. So I think I have enough ram.


      I have a 27" imac,

         • 2.9GHz  2.9GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cache,

         • 1TB (7200-rpm) hard drive

         • NVIDIA GeForce GTX 660M graphics processor with 512MB of GDDR5 memory


      Help please. Thanks.
