Raspberry Pi Speed Test

Just open up a terminal window on your Raspberry Pi and type the following at the command line, $ sudo apt-get install python-pip $ sudo pip install speedtest-cli this will install pip — a package management system for Python — if you don't already have it installed, and then the speedtest-cli package from the pip repositories.

• The ultimate Raspberry Pi network speed test compares best possible network options between all Raspberry Pi boards! There are four ways you can connect the internet to a Raspberry Pi board. You can use a built-in WiFi, add a WiFi dongle, use an Ethernet socket, or add one via USB. The Raspberry Pi network speed test covers the following boards.
• Start up agnostics from the menu within the Raspbian desktop. With the 'SD Card Speed Test' test selected (which it is by default), press the 'run test' button.
• Then reboot your Raspberry pi. Sudo reboot To see the updated speed, let's test it again with dd similar with previous test. $ dd if = /dev/zero of = test.bin bs = 10M count = 100 100+0 records in 100+0 records out bytes (1.0 GB, 1000 MiB) copied, 44.0051 s, 23.8 MB/s Now as you can see, the new write speed become 23.8 MB/s!
• Measuring speed on Raspberry Pi Speedtest.net has an official CLI client that you can install directly using apt. It selects the best server automatically and reports the download and upload speed, along with the latency of your connection.

Some of us will have multiple SD cards lying around. And sometimes it isn't obvious which one is the best to use.

Here is how you can check the speed of your SD cards which may help you with choosing the fastest one.

Raspberry Pi Performance Test

hdparm is a good tool to view disks reads, from the disk and from the buffer. We will use two options for hdparm;

1. The speed of reading directly from the Linux buffer cache without disk access. (-t option)
2. The speed of reading through the buffer cache to the disk without any prior caching of data. (-T option)

The first shows us an indication of the throughput of the processor, cache, and memory of the system under test. The second measures how fast the drive can sustain sequential data reads, without any filesystem overhead. It is also best to run this command multiple times to see the affect of the caching.

Need to install hdparm, and then run it at least twice.
From my output below, you can see that the response for the cached reads increased the second time I ran hdparm.

DD can also be used to test SD card speeds.
WARNING: you must be careful using DD as incorrect options can erase your SD card. After effects sketch animation maker.

This command will write a 200MB file called test to the SD Card;
dd if=/dev/zero of=test bs=1048576 count=200

This command will read the 200MB file created in the first command;
dd if=test of=/dev/null bs=1048576
