All,
More mysteries. To investigate this low insert performance under WinXP I
wrote a simple test program that loops writing one character to a file
and then flushing the file. The strange thing is that it seems to
alternate between two different run times as shown below. This is for 6
consecutive runs.
C:\Temp\test\Debug>test.exe
13 seconds, 77 flushes/sec
C:\Temp\test\Debug>test.exe
22 seconds, 45 flushes/sec
C:\Temp\test\Debug>test.exe
17 seconds, 59 flushes/sec
C:\Temp\test\Debug>test.exe
18 seconds, 56 flushes/sec
C:\Temp\test\Debug>test.exe
21 seconds, 48 flushes/sec
C:\Temp\test\Debug>test.exe
22 seconds, 45 flushes/sec
Initially performance is good but the degrades?
Some other processes must be sucking up cpu time?
