Hi,
When testing the RB2011UiAS-RM with LCD turned on I get random ping spikes and CPU runs +- 10% without passing any traffic.
Looking at tool>profile I can see SPI and unclassified +-5% each.
I know that SPI is for the LCD but a few versions earlier I don't think unclassified was involved, when turning the LCD off, both unclassified and SPI go to 0% and ping and CPU returns normal.
Also, my LCD is set to display only one screen and that is my WAN traffic, nothing else.
The ping spikes aren't high but It's just really annoying knowing that there are ping spikes and can also affect different traffic and also don't get the same throughput as I would when LCD off.
