When it goes slow, immediately bring up a terminal of your choosing and run:

dmesg

read the last 10 or so entrys, it may sho you whats going on.

I also recommend you run the memory tester in grub.

ok its right USB mouse device is really a low speed device...
on the first dmesg the kernel assign it as being an input10 but on next line it puts it on input0... ok i'm not an expert but it would be a bug or something ?!! not sure

Good outputs. You could try a different port maybe, or you could try some boot options to disable ACPI or DMA for example
