Webb21 okt. 2024 · The PostgreSQL shared_buffers is the major component of the shared memory used by the server. It is a large block allocated for caching blocks when reading from and writing to the database. This can be set via parameter that is called same – shared buffers. The default value for this parameter is 128 MB, which is fairly low. WebbA shared memory switch where the memory is partitioned into multiple queues.

BCC operates based on real-time shared buffer utiliza-tion. When the buffer is abundant,BCC delivers both high throughput and low packet loss rate. When it be-comes scarce, BCC triggers shared buffer ECN/RED to prevent packet losses at the cost of sacrificing a small amount of throughput. porch black glider chairs
