PERFORMANCE should be the default governor, for a long time it was on-demand..
If you know what USB devices you'll be plugging in, switch the MUSB
DMA mode from the cpu to cppi4.1 via:
diff --git a/patches/defconfig b/patches/defconfig
index 661d1a5..31a8caf 100644
--- a/patches/defconfig
+++ b/patches/defconfig
@@ -4601,7 +4601,8 @@ CONFIG_USB_MUSB_AM335X_CHILD=y

+CONFIG_USB_TI_CPPI41_DMA=y

You "will" lose compatibly with some usb devices. (most the wifi
ones..).. But for mass storage it should be fine..
