Performance degradation with deep call stacks (>50 frames)

[hokagedami]

Issue Description

I'm experiencing significant performance issues when using the CallStack enricher with deep call stacks containing more than 50 frames. The enricher seems to process each frame individually without any optimization.

Environment

• Serilog.Enrichers.CallStack: v1.0.353
• .NET 6.0
• Windows 11

Expected Behavior

Call stack enrichment should maintain reasonable performance even with deep stacks.

Actual Behavior

Processing time increases exponentially with stack depth. With 100+ frame stacks, enrichment takes >500ms.

Reproduction Code

Log.Logger = new LoggerConfiguration()
    .Enrich.WithCallStack()
    .WriteTo.Console()
    .CreateLogger();

// Deep recursion scenario
RecursiveMethod(100);

Would appreciate any insights on optimization strategies or configuration options to limit stack depth.

[hokagedami]

Thanks for reporting this! 500ms for 100+ frames is definitely too slow.

A few quick questions to help debug:

1. Are you seeing this in Debug or Release builds?
2. What's your logging volume when this happens?

As a temporary workaround, you might want to configure a maximum stack depth if that option exists. I'll investigate the performance characteristics and see if we can add some optimizations.

@hokagedami - have you run any performance profiling on the enricher? This seems like it could affect production workloads.
