When I try to build the teeny 4.1 encoder>speedTest.ino example I get the following error:

error: cannot convert 'volatile uint32_t {aka volatile long unsigned int}' to 'volatile unsigned char*' in initialization #define portOutputRegister(pin) ((digital_pin_to_info_PGM[(pin)].reg + 0))**

More detail on the error below.

Hardware & Software Board Teensy 4.1

Arduino IDE version 1.8.19

Teensyduino Version 1.56 for windows 7 and up (downloaded from teensyduino website today 3/22/2022)

The board is a Teensy 4.1

My operating system is Windows 10 pro

Arduino Sketch

Using the included encoder>speedtest.ino latest version, downloaded from https://github.com/PaulStoffregen/Encoder. The same error occurs with the version included with Teensyduino 1.56.

Example from the iperf3.txt file created.

[SUM] 0.00-30.00 sec 1.09 GBytes 312 Mbits/sec sender
[SUM] 0.00-30.00 sec 1.09 GBytes 312 Mbits/sec receiver

I would like to be able to "extract" the 312 Mbits/sec-text and leave the rest alone. Previous I've used this line of code to "present" the numbers from the iPerf-speedtest after the PS-script was completed, but the entire line is displayed like the example, I put in above.

Get-Content -Path $iperf3.txt | Where-Object {$_ -like'*[SUM]*0.00-15.00*'}

I've been looking at this post Get filtered content from text file with Get-Content and wondered if that is what is needed to do what I want.

I would like to end result to be something like this:

Your speedtest result is 123 Mbits/sec for download.
Your speedtest result is 321 Mbits/sec for upload.

Any input or feedback would be appreciated. Thanks!

EDITED/UPDATED
More text from the text-file.

For each speedtest iPerf will add the above content to the text-file, so in theory it will could be added two-three times. Hope this helps.

I am setting up some content blockers (https://developer.apple.com/documentation/safariservices/creating_a_content_blocker)

The HTML I am testing on looks something like this:

I have a console application project where i'm using the powershell SDK, it works perfectly fine in debug but on release, everything except powershell works.

The only settings i've found where it works is when releasing the project as framework dependent and portable. Or at least it works on my pc, on other computers it says the dotnet runtime is missing, even when installed via the link provided.

Using self contained, .net6-windows and win-x86 doesn't work. Not quite sure what could be wrong? I've tried cleaning the project, the solution, restarting visual studio and my PC. Everything works as expected in debug but when I publish, powershell just doesn't work.

I'm making a internet speedtest app with Node.js. Everything works fine expect the download test. I normally download at 8Mbits/s but when I try XHR requesting a text file / image (about 256 MByte) at /public/chunk/somefile.txt for example, it downloads it within 1 second which is impossible. Then I checked the onprogress log:

How comes that it loads the image so fast? I mean it isnt cached or anything. Anyways here's the code:

I have an image that performs a query on BigQuery and then downloads the result (about 8GB) with the following code:

I am new to Kotlin and Jetpack Compose. I am trying to display data from a data class depending on the row that the user clicks. The way I have it set up now is the data is remembered, but the user has to click the text box, and then click the row to get the data to show up in the card. It is set up like rows in a table.

I am trying to clone the linux kernel, the transfer speed seems perfectly fine, but curl always aborts:

I want to understand how to determine whether my internet connection is a bottleneck or not during a jmeter stress test.

Here is a bit of background for my problem:

I made a stress test with a 2 hours duration, with 2000 threads ramped up over the whole 2 hours duration hoping to find the upper limit of the server, but I am thinking that maybe I hit some other limit and not the server's, as it's not shutting down, aka not responding with 4xx or 5xx error codes. I can only see in the report that the transactions per second go fairly quickly to 580, but they then will not go above.

When I run the stress test against one server endpoint and the load keeps increasing, I need to be connected to a VPN to have access to that endpoint.

Most of the stress test runs I tried, behave like this:

Although, the number of threads increases, like this:

And I only have Non-HTTP error response codes which are not reflected in the server logs, aka the server reports no 4xx or 5xx error codes:

The server will not go over 580 TPS, but it will not throw errors either:

As per this site, my internet connection (via cable or wifi, I see no major difference) has 1ms ping, 400-420 Mbps download capacity and around 250 Mbps upload capacity - granted, this is calculated with some server selected by them, located relatively near to my location.

How can I know how much of that "pipe" capacity is being used so that I can say with certainty that my internet connection is not a bottleneck? Can the VPN be a bottleneck?
