Downloading large file

Hello, I need to be able to download files up to 400Mb asynchronously and track the download in a progress bar. I have this code except that it doesn't work totally, on 50Mb files it's fine but 130Mb it crashes and moreover it takes a while before starting the download. So I wanted to know if this was the right method and if it was possible to optimize it?

c#
int DefaultCopyBufferSize = 81920;
string destinationPath = Path.GetTempFileName();
using var client = new HttpClient();

using var response = await client.GetAsync(url);
response.EnsureSuccessStatusCode();
using var source = await response.Content.ReadAsStreamAsync();
using var destination = File.OpenWrite(destinationPath);

int bytesRead;
var buffer = ArrayPool<byte>.Shared.Rent(DefaultCopyBufferSize);
var memory = buffer.AsMemory();

while ((bytesRead = await source.ReadAsync(memory)) > 0)
{
    await destination.WriteAsync(memory[..bytesRead]);
    progress.Increment(bytesRead);
}

Most optimized download system

Hi, I need to download a file separated into different chunks (between 100 and 400 mb each) from a server and make it as fast as possible. Except that I'm a bit confused, I've seen that there are lots of different methods for downloading files, with the added bonus of possibly downloading more than one at the same time. I was wondering if you had any advice on how to go about it? The code I'm currently using:

ProgressTask progress = ctx.AddTask("Downloading chunks", true, fileInfos.size);
                
AnsiConsole.MarkupLine($"[gray]LOG: [/] Started download of [blue]{fileInfos.chunksCount}[/] chunks");
for (int i = 1; i <= fileInfos.chunksCount; i++)
{
  await DownloadChunk(fileInfos.host, fileInfos.wd, fileInfos.id, i, fileInfos.chunkSizes[i - 1], progress);
}

AnsiConsole.MarkupLine("[yellow]Assembling chunks...[/]");
CombineChunks(tempDir, Path.Combine(downloadDir, fileInfos.filename), fileInfos.id);

ProgressTask progress = ctx.AddTask("Downloading chunks", true, fileInfos.size);
                
AnsiConsole.MarkupLine($"[gray]LOG: [/] Started download of [blue]{fileInfos.chunksCount}[/] chunks");
for (int i = 1; i <= fileInfos.chunksCount; i++)
{
  await DownloadChunk(fileInfos.host, fileInfos.wd, fileInfos.id, i, fileInfos.chunkSizes[i - 1], progress);
}

AnsiConsole.MarkupLine("[yellow]Assembling chunks...[/]");
CombineChunks(tempDir, Path.Combine(downloadDir, fileInfos.filename), fileInfos.id);

DownloadChunk:

using (var client = new WebClient())
{
  long previousBytesReceived = 0;
  client.DownloadProgressChanged += (sender, e) =>
  {
     progress.Increment(e.BytesReceived - previousBytesReceived);
     previousBytesReceived = e.BytesReceived;
  };
  client.DownloadFileCompleted += (sender, e) => AnsiConsole.MarkupLine($"[gray]LOG: [/]Finished download of chunk [green]{chunkNumber}[/]");
  await client.DownloadFileTaskAsync(new Uri(url), destinationPath);
}

using (var client = new WebClient())
{
  long previousBytesReceived = 0;
  client.DownloadProgressChanged += (sender, e) =>
  {
     progress.Increment(e.BytesReceived - previousBytesReceived);
     previousBytesReceived = e.BytesReceived;
  };
  client.DownloadFileCompleted += (sender, e) => AnsiConsole.MarkupLine($"[gray]LOG: [/]Finished download of chunk [green]{chunkNumber}[/]");
  await client.DownloadFileTaskAsync(new Uri(url), destinationPath);
}

Discord.js RPC Extension work ?

I found this extension https://github.com/discordjs/RPC/ for discord.js which allows the use of rpc, which leads me to 2 questions: the last update of the project was 3 years ago and the documentation is no longer available, does it still work. And secondly, can I use it to activate the rpc on people who connect to my web page?
