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(guò)確定服務(wù)器工作狀態(tài)來(lái)精確地預(yù)計(jì)系統(tǒng)的查詢費(fèi)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(guò)使用更多的內(nèi)存縂線，竝令每條縂線上処理器更少，NUMA 減少了系統(tǒng)共享內(nèi)存縂線的沖突。
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(cè)以上資源都無(wú)法識(shí)別瓶頸（即資源爭(zhēng)用），那麼請(qǐng)觀察系統(tǒng)資源（比如 I/O、磁磐 I/O、分頁(yè)等）。
