 Since the sysfs GPIO interface is rather slow and we make things
 worse by swapping to compressed RAM, the loading of fjmem.bit
 takes about four or five minutes.

+Going faster
+------------
+
+In many applications, UrJTAG will be able to run without compressed
+swap and thus faster. Smaller amounts of data will also make even
+slow transfers more bearable.
+
+To further increase the speed, a Ben-specific GPIO driver could be
+written that accesses registers directly without the very long
+detour through sysfs.
+
+Finally, even higher speeds could be reached by using the MMC
+controller to send data, similar to UBB-VGA. For this purpose, CMD
+and DAT0 have been left unconnected. When connecting them to each
+other, they could be used to generate fake start bits, signaling
+the MMC controller to begin a transfer. (See ubb-vga for details.)
