I have an RPi 4 4GB and I'm running RPi 64bit OS from a NVME HD connected via USB.
When remoted in via VNC, everything is very slow. It takes about 10s to open the browser. I remote in using the local home network and the RPi is connected via WiFi.
From my on-line research, everybody always points the finger to the SD card, hence I'm trying an NVME drive.
These are my results from the
pi@raspberrypi:~ $ sudo hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 1920 MB in 2.00 seconds = 960.75 MB/sec Timing buffered disk reads: read(2097152) returned 524288 bytes
I also checked that the RPi is not being throttled:
pi@raspberrypi:~ $ vcgencmd get_throttled throttled=0x0
What else can I try to improve the VNC performances?
