3144 is about 50% of what that CPU should do, so still worrisome. If you can select the performance power plan, edit it and check that it is set to allow 100% of the CPU and graphics to be used. Run a test of the tablet while plugged in to power outlet. Now more importantly, did you by any chance buy the Docking cradle, as there is a possibility that when in that cradle the tablet is allowed to use more CPU. Thank you in advance for spending time on this and getting on Fujitsu case, because we love that tablet, but only getting 50/ 60% of the CPU performance is really not exciting.
