philipljackson 0 Posted February 2, 2019 Hi Environment 10.2.2 enterprise on Windows 10 professional When compiling my applications I have recently noticed a 50+ second delay in the compilation process, which I believe is waiting for rtutils.dll or combase.dll (?) to finish and exit a thread. Fortunately this does not occur on user applications but just my development machine. I have used procmon.exe to watch the compilation process and below are sample events This is where thread ID 3996 is created <event> <ProcessIndex>515</ProcessIndex> <Time_of_Day>15:17:51.7721871</Time_of_Day> <Process_Name>Alarm.exe</Process_Name> <PID>6564</PID> <Operation>QueryNormalizedNameInformationFile</Operation> <Path>C:\Windows\SysWOW64\combase.dll</Path> <Result>SUCCESS</Result> <Detail></Detail> </event> <event> <ProcessIndex>515</ProcessIndex> <Time_of_Day>15:17:51.7721984</Time_of_Day> <Process_Name>Alarm.exe</Process_Name> <PID>6564</PID> <Operation>Thread Create</Operation> <Path></Path> <Result>SUCCESS</Result> <Detail>Thread ID: 3996</Detail> </event> <event> <ProcessIndex>515</ProcessIndex> <Time_of_Day>15:17:51.7723309</Time_of_Day> <Process_Name>Alarm.exe</Process_Name> <PID>6564</PID> <Operation>Load Image</Operation> <Path>C:\Windows\SysWOW64\combase.dll</Path> <Result>SUCCESS</Result> <Detail>Image Base: 0x76fe0000, Image Size: 0x278000</Detail> </event> This is where thread ID 3996 is finishes, note the 56 second delay between the two events below <event> <ProcessIndex>515</ProcessIndex> <Time_of_Day>15:17:55.4613083</Time_of_Day> <Process_Name>Alarm.exe</Process_Name> <PID>6564</PID> <Operation>RegCloseKey</Operation> <Path>HKLM\System\CurrentControlSet\Control\SQMServiceList</Path> <Result>SUCCESS</Result> <Detail></Detail> </event> <event> <ProcessIndex>515</ProcessIndex> <Time_of_Day>15:18:51.7779281</Time_of_Day> <Process_Name>Alarm.exe</Process_Name> <PID>6564</PID> <Operation>Thread Exit</Operation> <Path></Path> <Result>SUCCESS</Result> <Detail>Thread ID: 3996, User Time: 0.0000000, Kernel Time: 0.0156250</Detail> </event> Advice most welcome as this is wasting a lot of my time.
