Scan speed S L O W using gqrx-scan

[w1av]

I am using gqrx-scan with 6 conventional UHF (fire/Police) frequencies. It works great but is the any way to speed up the rate that it scan thru those 6 freqs? I tried changing value on command line but it doesnt do much. Here is the command I use to start the program:

perl gqrx-scan --type gqrxfile --pause 0.1 --wait --delaytime 0.2

I changed "pause" to a lower value but it didnt speed up scan. Is there any way I can modify this perl script to improve things? Also while scanning, the fft stutters, and stops between each freq scan. I mean I can live with it the way it is and I don't have very good experience with perl. Any suggestions?

Buy a real scanner ?  These rtl-sdr aren’t setup for high speed scanning.  Or buy more dongles
