Frequency Range

Your PlutoSDR can be fooled into thinking the chip is the AD9364 which gives an expanded frequency range of 70MHz to 6GHz [Link]

2nd CPU Core

You can also enable the second CPU core, although it is not known if this improves performance.

Connect with a terminal emulator (for example Putty) to the Pluto serial port.

Username=root, password=analog
cat /proc/cpuinfo shows just one CPU - processor 0

Enter:
fw_setenv maxcpus
pluto_reboot reset

After the reboot login again and cat /proc/cpuinfo shows two CPUs - processors 0 and 1

And example of the output from these commands is available here:
