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 startup etc. are not meassured. Of course, some settings and the number of matches have impact on the perfomance as well.
