redis 处理“N”个连接的能力？

Question

如果对 Redis 有任何性能测量 它可以同时处理多少个订阅/频道？

Answer 1

我还没有看到这方面的基准，但推送到订阅频道的复杂性在 O(N) 系列中。 来自文档：

发布：

O(N+M) where N is the number of clients subscribed to the
receiving channel and M is the total number of subscribed 
patterns (by any client).

PSUBSCRIBE（订阅模式）：

O(N) where N is the number of patterns the client is already subscribed to.

订阅：

O(N) where N is the number of channels to subscribe to.
