What will be the performance impact on my Celeron 1.73 GHz CPU and/or hdd speed?

To further add to what has been said, check if your particular CPU supports the AES-NI instruction set which should provide some performance boost:

Of course, that is, if you choose to use the AES cipher (the default).

My laptop is 3-4 years old, no AES addon in it. And I can see only high end CPU's have them, so I will not be buying one sore several years (I also use laptop in the field, grain silos, etc so I will not buy anything that is expensive).

But thanks for the info, to all of you of course.
