我正在调查通过网络访问文件时的延迟。这是网络监视器给我的顺序：
16848 08:42:17 System SERVER CLIENT SMB2 SMB2:N OPLOCK BREAK (0x12) {SMBOverTCP:49, TCP:48, IPv4:47}
17408 08:42:22 System SERVER CLIENT SMB2 SMB2:R CREATE (0x5) Interim Response, File=Storage\file@#16844 {SMB2:87, SMBOverTCP:42, TCP:39, IPv4:26}
// some unrelated events
20123 08:42:47 System SERVER CLIENT SMB2 SMB2:R CREATE (0x5), MxAc+RqLs(RH), FID=0x2(Storage\file#16844) {SMB2:87, SMBOverTCP:42, TCP:39, IPv4:26}
20124 08:42:47 System CLIENT SERVER SMB2 SMB2:A OPLOCK BREAK (0x12) {SMBOverTCP:42, TCP:39, IPv4:26}
20125 08:42:47 System SERVER CLIENT SMB2 SMB2:R OPLOCK BREAK (0x12) {SMBOverTCP:42, TCP:39, IPv4:26}
在OpLock超时（30秒）后立即发送OpLock确认的原因可能是什么？
可以从Windows服务和在同一台计算机上运行的应用程序（客户端）中使用相同的用户帐户访问相同的文件。
