Hi David and all, CPU usage running 700D Ver 3572 is quite OK, 100% of one CPU of a Quad Core.
I run a Quad Core box: ASRock QC5000/ITX a Low Power motherboard vendor_id : AuthenticAMD cpu family : 22 model : 0 model name : AMD A4-5000 APU with Radeon(TM) HD Graphics stepping : 1 microcode : 0x700010b cpu MHz : 800.000 cache size : 2048 KB fpu : yes fpu_exception : yes bogomips : 2994.54 top - 18:32:54 up 115 days, 4:43, 4 users, load average: 1.46, 1.13, 0.70 Tasks: 291 total, 3 running, 288 sleeping, 0 stopped, 0 zombie %Cpu(s): 31.8 us, 4.2 sy, 0.0 ni, 63.9 id, 0.0 wa, 0.0 hi, 0.1 si, 0.0 st KiB Mem : 7592440 total, 205480 free, 1813748 used, 5573212 buff/cache KiB Swap: 8191996 total, 6313456 free, 1878540 used. 5352648 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 28410 alanb 20 0 1205880 56316 38656 R 96.4 0.7 5:33.78 freedv 11081 alanb 20 0 368284 43696 27040 S 14.9 0.6 282:15.78 Xorg This should be indicative of a modern laptop.
