Dear Elisa,
it depends on the organisation of your DICOM data how much resources SPM needs to convert them. SPM reads all DICOM headers first. In a second step the headers are sorted into 3D volumes and written to NIfTI files. Instead of entering all of your DICOM files at once, you can guide SPM by selecting them series- or even volume-wise (maybe using a combination of batch and script code).
Best,
Volkmar
