UnverifiedOn the test machine, FastGPT's memory usage at idle is about 2.1 GB, a VPS with 2GB RAM would struggle even to start, and a machine with at least 4GB of memory is recommended.66% similarUnverifiedWhen FastGPT's knowledge base document count exceeds tens of thousands or concurrent users exceed a few dozen, it is recommended to use 8GB of memory or a separate database instance directly, otherwise it easily triggers the OOM Killer and causes containers to be forcibly terminated by the system.64% similarUnverified片上SRAM提供了远超HBM的访问速度和带宽，消除了芯片到外部内存之间的数据搬运瓶颈64% similarUnverifiedAt very large scale datasets, pgvector's performance based on IVFFlat or HNSW indexes is often constrained by single-machine memory and CPU resources, making horizontal scaling difficult.64% similarUnverifiedPostgreSQL 每个连接通常需要消耗数 MB 的内存61% similar
