The ripping speed depends on many factors. Different drives have different audio extraction speeds. That is not necessarily relative to the data CD reading speed. After the audio is extracted the CPU and HD speed are the next factors that make differences.
As a test you could rip a CD in wave format and convert the files to Monkey's Audio in a separate process. Compare the ripping and converting times with the ripping time you got when you ripped directly in Monkey's Audio format.
If ripping in wave format is much faster you could rip a bunch of CDs using wave format and let your PC convert them unattended afterwards.
Generally I think the speed you got is normal for a laptop. A faster CD drive or perhaps a faster HD (firewire or USB2) could help, but there is no way to know that without testing on your system.
This looks a bit suspicious to me:
Intel Unknown 575 MHz MMX
but I suppose the low number is because of the way a laptop CPU reports its speed.
If you are going to archive your lossless files you really should use the secure mode and rip logging. Otherwise you have no means of knowing if the CDs were ripped without errors before listening to them. Using the Secure mode makes ripping a bit slower (not necessarily much if the CDs are in good condition), but that is for good reason. Did you check these links I already provided in the other thread?
