PCr and PCd are average 2.6 GHz Pentium 4 PCs with 512MB and 1024MB RAM. Sizes of images vary from small (320 x 320) to large (3262 x 2448). Approx 45000 images occupy 4.5GB of disk space (one DVD). Other times like cache reload time, program start-up etc. are not measured. Of course, some settings and the number of matches have impact on the performance as well.
