lecroy scope save waveform works slowly

Good day everyone,

I am using Lecroy 6051A scope and it seems to me, that saving waveform works too slowly. I have written a program for my Lecroy and there have a loop with N=100 to save 100 waveforms. It takes around 20 seconds to do so, which, as it seems to me, is too much. I want to be able to save at least 20 waveforms in 1s. 

I have attached my vi. I use 1 channel, timebase was 200 ns/div (250Ms/s). I was advised to use VICP descriptor instead of TCPIP, as it should work faster with VICP

I was trying to delete all the vis in my programm except for those in the 'for' loop, but still it was almost 20 seconds to save 100 waveforms. I am new in working with Labview, maybe I am doing smth wrong, could anyone help me please?
