Take a look at this thread:

> Hello everyone, We’re developing a C++ receive-only application with the LimeSDR mini, and we’re having a bit of a throughput problem. First, here’s how we’re setting up the SDR, simplified/pseudo-code but I tried to include all the pertinent details. LMS\_Open(…) LMS\_Init(…) LMS\_EnableChannel(device, LMS\_CH\_RX, 0, true) LMS\_SetLOFrequency(device, LMS\_CH\_RX, 0, 97e6); //center frequency 97 MHz LMS\_GetAntennaList(…) LMS\_GetAntenna(… LMS\_PATH\_LNAW) LMS\_SetSampleRate(… 192e5) LMS\_SetLPFBW(…

My CPU is AMD Ryzen 5 1500X (CPU mark 8,991), Win10 Home 64bit and process 30MHz BW without problem using SDR# (try to find 64bit version - it is much faster!). SDR console use same shark.dll for decimation process (critical process for this type of SDR application) plus CUDA support (optional for Nvidia GPU owner). Simon, author of SDR console, can explained better program critical parts.  
For reference above mentioned I3-6100 has 4,182 CPU mark points and i7-2675QM only 3,162!
