ST7735 at high rate?

i tried with an hardware spi, but I don't save much time. 1 tenth of a second

SPI2.setup({mosi:B15 /* sda */, sck:B13 /* scl */, baud:integer=1000000,});
  g =require("ST7735").connect({
    palette:colorPalette,
    spi:SPI2,
    dc:A7,
    cs:B10,
    rst:B1,
    padx:2,
    pady:3
    // height : 160 // optional, default=128
    }, ecrit
  );
