contention system

基本解釋

This method can accurately predict the system contention state so that to estimate the cost of a query precisely.
該方法可以通過確定服務(wù)器工作狀態(tài)來精確地預(yù)計系統(tǒng)的查詢費用。
NUMA reduces the contention for a system's shared memory bus by having more memory buses and fewer processors on each bus.
通過使用更多的內(nèi)存總線，并令每條總線上處理器更少，NUMA 減少了系統(tǒng)共享內(nèi)存總線的沖突。
If probing for the above resources does not identify any bottleneck (i.e., resource contention), observe the system resources (like network I/O, disk I/O, paging etc.).
如果探測以上資源都無法識別瓶頸（即資源爭用），那么請觀察系統(tǒng)資源（比如 I/O、磁盤 I/O、分頁等）。
