Plugin Overview & Capabilities

AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.

source-grounded
dsh-large-proj-perf is an installable DSH performance plugin for very large sessions. It monkey-patches DSH rc.6 internals to reduce blocking during forks, projection initialization, and persistence materialization, while providing runtime configuration and statistics APIs.

Key Capabilities

  • Uses zero-copy fork and fast persistence initialization paths to avoid some deep-copy work.
  • Warms session projections in chunks, yielding to the event loop between chunks.
  • Writes fork projection cache entries after warmup.
  • Materializes persistence data in chunks using multiple zstd frames.
  • Trims the prepared cold-session cache with a configurable LRU capacity.
  • Warns when the detected V8 heap limit is below a configured threshold.
  • Provides HTTP APIs for runtime statistics and configuration.

Useful For

  • Reducing fork latency for DSH sessions with very large event histories.
  • Avoiding single huge serialization strings during fork-session materialization.
  • Prewarming projections before synchronous cold folding blocks the event loop.
  • Limiting memory retained by prepared cold-session caches.

Who It Fits

  • DeepSeek Harness users operating unusually large or long-lived sessions.
  • DSH operators who can validate logs and adapt version-coupled patches after upgrades.

Documented Limitations

  • Highly coupled to DSH 0.1.0-rc.6 internal structures; source-signature mismatches skip optimizations and fall back to official behavior.
  • It cannot eliminate all event-copying work, including the per-event structuredClone in enqueue.
  • Cold-session readFrom(0) decoding and stored-event copying cannot safely be chunked by this plugin.
  • Very large sessions can still cause memory pressure or OOM because live event trees remain fully resident.
  • Its tests require DSH internal packages available from a global DSH installation and a dependency-linking step.

DSH Compatibility

Version-specific runtime evidence collected by DSH Plugin. A missing result means we have not tested that combination yet.

Security Signals

Objective signals discovered from package metadata and source inspection. These are not a guarantee that a plugin is safe.
