Net garbage collection and the internal mechanism of garbage collection to perform a Finalize method; we look at weak reference objects, generation, multi-threaded garbage collection, large object processing, and performance

Statistics User Connections Displays the current number of connections to SQL Server, not the number of users. If the counter exceeds 255, then you need to set the configuration value of SQL Server's Maximum Worker Threads to be higher than the default value of 255. If the number of connections exceeds the number of threads available,

following is the optimization of the SQL statement in fact, SQL is not complex, but the data of these tables are slightly larger, but also nested inside more complex business logic, history after several rounds of "master" in the index of the whole side of the optimization, can also run normally but over time, the amount of data in the table is getting larger , boiled frog in warm water,

by the counter data. The offset of the counter data relative to the perf_counter_block is defined in each perf_counter_definition structure, so the value of all counters can be easily obtained. For multi-instance performance objects, the perf_counter_definition structure list is followed by a set of instance information data blocks, each representing an object instance. Each instance information data block

expectancy: the expected time (in seconds) for the SQL Server to load the page to the buffer pool ). When the memory is tight, data pages need to be cleared frequently, so Microsoft recommends 300 seconds. However, when the memory is sufficient, it can easily reach thousands of seconds. I looked at the three counters in my notebook and found that total (= 60.67
