内存泄漏问题 #59
Description
- 模拟数据 插入以下结构的大约数据 1万个
exhset us:126902 session:dea155d63828f002484fb2d67a879c81 "" EX 60 - 查看每个数据占用内存情况 (大约152)
127.0.0.1:6379> memory usage us:105681
(integer) 152 - 但总内存占用 100M
127.0.0.1:6379> info memory
Memory
used_memory:105388744
used_memory_human:100.51M
问题：按道理算 10000 * 152 = 1.449M 那为什么会占用 100M内存
测试了三种模式，都是占用这么多内存，希望得到回复
