Blazor server communications optimisation

I am working on a blazor server web application.

I have to display a table with a big number of rows and columns.

I want to optimize.

Is there a way to enable data compression on blazor's websockets ?

Is there a compression enabled by defaut in Developpment or Production environnement ?

Thanks

Unsure if this is going to be best answer for this but figured I would post it anyway. As other's have commented it would be best to utilize virtualization or pagination along with other app optimizations, but your question made me curious.

After a quick google search turns out asp.net has response compression.

The code used (Placed both as the very first things in their respective methods):

  • In Setup/ConfigureServices:

         services.AddResponseCompression(o =>
     {
         o.EnableForHttps = true;
         o.Providers.Add<BrotliCompressionProvider>();
         o.Providers.Add<GzipCompressionProvider>();
         o.MimeTypes = ResponseCompressionDefaults.MimeTypes.Concat(
             new[] { "image/svg+xml" });
     });
     services.Configure<BrotliCompressionProviderOptions>(options =>
     {
         options.Level = CompressionLevel.Optimal;
     });
     services.Configure<GzipCompressionProviderOptions>(options =>
     {
         options.Level = CompressionLevel.Optimal;
     });

  • In Setup/Configure:

        app.UseResponseCompression();

Default Blazor server app:

  • Default: 2.2kB transferred.

  • With changes: 1.5kB transferred.

Loading my own Blazor server app and testing it:

  • Default: 5.4kB transferred

  • With changes: 3.7kB transferred

Overall these changes appear to compress what is being transferred a bit more and the compression could most likely be even further optimized, but these changes should not be a substitute for optimizing your code.
