Is there a possibility to force IM to use more memory? Simple operations like canvas extension (-bordercolor black -border 5%x5%) take a lot of time due to disk caching. Thank you for your response.

Thank you for your reply. Well, the solution was quite easy, but it didn't strike me at first - I was using the portable version of IM, which is 32-bit and for some reason this version was able to use only up to cca 1.5G memory. After installation of 64-bit version, IM was able to allocate more than 5GB of memory for itself.
