redis 请求慢
time redis-cli -h 127.0.0.1 -a 123456 ping PONG real 0m2.314s user 0m0.000s sys 0m0.002s
不是每次都慢,大概5、6次操作中会出现一次超过秒。以下是redis信息
used_memory:3646312 used_memory_human:3.48M used_memory_rss:10051584 used_memory_peak:4901784 used_memory_peak_human:4.67M used_memory_lua:31744 mem_fragmentation_ratio:2.76 mem_allocator:jemalloc-3.2.0 # Clients connected_clients:1 client_longest_output_list:0 client_biggest_input_buf:0 blocked_clients:0
开启redis的错误日志,但是没有发现有执行慢的命令。服务器信息

这台服务器是测试机,公司人员也不多,请求量不会大。服务器tcp连接数维持在100以下。
