我使用 sqlite
数据库进行存储。同时也有许多数据库事务。我的问题是,sqlite 页面缓存的内存使用量会迅速增长。在 instruments
中,我可以找到以下这行代码:
Graph Category Live Bytes # Living # Transient Overall Bytes
0 VM: SQLite page cache 12.12 MB 97 1434 191.38 MB
在其中有97个以下文件
# Address Category Timestamp Live Size Responsible Library Responsible Caller

8 0x573d000 VM: SQLite page cache 01:41.550.465 • 128.00 KB libsystem_kernel.dylib vm_allocate
任何关于是什么原因导致这种情况或如何删除这些文件的想法都将不胜感激。谢谢!
