Why is my Raspberry Pi running so slow?
This might of course also be due to firmware changes (I am running the tests over multitasking OS in a SSH shell, after all). Also, a /proc/sys based access method was provided, but it was a lot slower, running at 120 kHz on average (200 kHz). The wiringPi library also has Python, Ruby and Perl bindings.
Why does cups lpd utlimate give a long delay?
It seems that printing a single page one time give no delays, but if I try to print say, 20 copies of the same page, it seems that it’s generating the whole 20 pages, thus giving a very long delay. Edit 2: Here is my debug info: http://pastebin.com/yZFgP66v
How to test the GPIO speed of a Raspberry Pi?
Here are the current results: The easiest way to manipulate the Pi GPIO pins is via console. Here’s a simple shell script to toggle the GPIO 4 as fast as possible (add sleep 1 after both to get a nice LED toggle test): As expected, the performance of this implementation is not good: A 2.9 kHz square wave can be generated using this method.
How does hpijs work with cups lpd utlimate?
Both data paths will use the “hp” backend. For the HPIJS path, look for errors near the ghostscript command (gs) command. The gs command will invoke the HPIJS driver. For the Postscript path, there will be no gs command. Postscript will be passed directly to the “hp” backend and then to the printer.
The Raspberry Pi has network hardware hanging off a USB controller, and needs the support of the not-very-brawny CPU to handle every byte. It’s probably not the computer for this job. Something like a GuruPlug Server (if they’ve fixed the power supply/overheating problems that plagued earlier GlobalScale Plugs) might be better.
What’s the maximum speed of a Raspberry Pi?
Just for lulz, I ran a Java speedtest from DSLreports.com on my Raspberry Pi. It maxed out at 5.2m/2m.
How can I get more downloads on my Raspberry Pi?
I run a proxy on my pi via ssh dynamic port forwarding, and I can get up to 5Mb/s downloads and 1Mb/s uploads via qbittorrent on windows. (Attempted with Linux mint’s Iso).
