## MemoryBench parallel execution and MCP connection reliability[#](https://supermemory.ai/changelog/2026-01-05-improvements-and-fixes)

MemoryBench can run benchmark phases concurrently with separate concurrency controls per phase, and MCP and streaming connections retry brief server overloads before returning a temporary-unavailable error.

### Improvements

* [MemoryBench can run benchmark phases concurrently, with separate concurrency controls for ingest, indexing, search, answer, and evaluation.](https://github.com/supermemoryai/memorybench)

### Fixes

* MCP and streaming connections now retry brief server overloads before returning a temporary-unavailable error.
