Hi @jhoogstraatLHIND . Thanks for opening this issue. We will investigate this problem!

[jhoogstraatLHIND]

Great!

I just noticed it does load eventually, it just takes minutes on my machine and the graph is horribly slow.

@jhoogstraatLHIND which version are you using? are you self-hosting tracetest or using app.tracetest.io? I remember seeing a similar behavior, but we released a fix a couple of versions ago.

Edit: we released a performance patch for parsing a large number of spans in v0.13.9

Hi @jhoogstraatLHIND, thanks for reporting this. The team is working on identifying the bottlenecks to support that amount of spans, but we are also trying to propose a UI graph that makes sense for big traces.

It would be really helpful if you can share with us your 8K spans trace. Please let me know if that is possible.

The team is prioritizing this work. We are doing some planning and will update this ticket with tasks and progress.

That's great to hear. We are still evaluating Tracetest.

On a similar note:
When the request or response bodies get very long the applications slows down to a crawl.
Maybe a move to MS Monaco Editor would already do the trick.

Thanks @jhoogstraatLHIND We will take a look at those performance issues as part of this work.
