generally the more the better, sometimes we may force some data pin in the cache. However, if there are other applications, although MSSQL will release the memory when needed, it also takes time to switch the thread and wait for Io, which will lead to performance degradation. In this way, you must set the maximum memory usage of MSSQL. You can find the maximum memory

compression is 167M, the size of the table after compression is only 40% of the original table, the effect is obvious, and because most of the table's fields are only IDs, the relative repetition value is not too much.However, we see that the size of the index varies substantially, so we continue to compress the index:5. Compression indexAlter index idx_tb_wcb_id on Tb_wcbrebuildwith (Data_compression=row)
