Re: When are people in the U.S. getting their Pi 4s?

The 4GB model is proving very popular, more so than we expected. The 2GB is the sweet spot for desktop. Or so we thought... Just curious why you thought that ... I'm with HawaiianPi and maybe some others in thinking that the model with 4 GB RAM would be the sweet spot for desktop performance (from ...

Re: Pi4 as Desktop computer

Wren: Those images in the upper right window of your screen capture look rather morbid and disturbing. You might want to pick something else when illustrating multiple windows here. Sorry if this seems prudish but it looks like a bunch of crime scene photos of murdered human beings to me.

To a degree, yes, however setting that aside it also requires you to use slightly inferior tools, can you get Firefox Quantum running on a Pi?

Re: Why is the RPi4 being advertised as a desktop computer?

The Pi 4 is being advertised as "Your tiny, dual-display, desktop computer" that can do anything your current computer can but is just slower and more power efficient. But on the Desktop side of things, it's ARM processor makes it too incompatible with anything to make it a real desktop computer. P...

Thank you, epoch1970 - looks like I have some testing to do. I appreciate the caution that some tests might actually be indirectly testing the speed of my SD card rather than network speed. Obviously that would make a huge difference!

Please help me troubleshoot my 3B+ with respect to internet speeds via wifi and ethernet. In short, it's only getting about 10% of my ISP service's 300 Mbps speed, even when connected via ethernet cable (as opposed to wifi in the house).

My fiber optic service is 300 mbps. [that's not the max available, that's just what we pay for].

Not sure what my "gigabit" router then does in terms of attenuating that speed.
