Eccet utilizes - depending on the size of the volume dataset - rather high processing power. For larger datasets (about 512x512x512 voxels) we recommend processors of 2GHz and higher. Optimal performance for smooth animation speeds will typically require about 3GHz of total processor speed.

Smaller volumes (like 256x256x256) are typically viewable with processors of around 1GHz.

Eccet supports symmetric multiprocessing and multi-core CPUs. Most functions reach the speed that results from the sum of all processor speeds.
Thus a 2x2GHz machine should be about equivalent to a hypothetical 4GHz machine.

Eccet requires (depending on the mode used) 2-4 Byte memory per voxel.
This means, that for the typical 512x512 pixel slices, you will need 1MB per slice. You have to add around 200MB for the operating system and Eccet itself.
For the windows platform, an additional 200-400MB are required for the host OS and the virtualization environment.

Thus we recommend to have at least 1GB of memory.
Unused memory does normally not significantly speed up the system, but may e.g. be used to view multiple datasets in parallel.
On 32-bit architectures, as they are common for nowadays PCs, pushing the amount of memory beyond 2GB usually makes no sense, as single processes cannot get more than 4GB and much of this space is already reserved for other purposes.
