cool!

The startup delay for `fossil ui' and `fossil server' on Windows XP is
more obvious than possibly sluggish browser navigation, which I
*think* is due to waiting for StartServiceCtrlDispatcherW. This could
be cut down by skipping the call to StartServiceCtrlDispatcherW for
the `ui' and `server' commands, as Fossil always runs in a console
session, and not as a service, in these cases.
I measured the time it takes to call StartServiceCtrlDispatcherW on my
8 year old Windows 7 64bit box: roughly 600 microseconds, I don't think
this is noticeable!
This is the program for taking the time:
***** Start of code *****
#include <stdlib.h>
#include <stdio.h>
#include <inttypes.h>
#include <windows.h>
static void WINAPI win32_http_service_main(
DWORD argc,
LPWSTR *argv
){
return;
}
int main(void){
LARGE_INTEGER Frequency;
LARGE_INTEGER StartingTime;
LARGE_INTEGER EndingTime;
LARGE_INTEGER ElapsedMicroseconds;
double ElapsedSeconds;
int rc = 0;
/* Define the service table. */
SERVICE_TABLE_ENTRYW ServiceTable[] =
{{L"", (LPSERVICE_MAIN_FUNCTIONW)win32_http_service_main},
{NULL, NULL}};
/* Get frequency and the start time. */
QueryPerformanceFrequency(&Frequency);
QueryPerformanceCounter(&StartingTime);
/* Activity to be timed */
if( !StartServiceCtrlDispatcherW(ServiceTable) ){
if( GetLastError()==ERROR_FAILED_SERVICE_CONTROLLER_CONNECT ){
rc = 1;
}else{
rc = 2;
}
}
/* Get end time and convert to seconds. */
QueryPerformanceCounter(&EndingTime);
ElapsedMicroseconds.QuadPart = EndingTime.QuadPart
- StartingTime.QuadPart;
ElapsedMicroseconds.QuadPart *= 1000000;
ElapsedMicroseconds.QuadPart /= Frequency.QuadPart;
ElapsedSeconds = (double)(EndingTime.QuadPart
- StartingTime.QuadPart)/Frequency.QuadPart;
printf("Elapsed microseconds: %"PRId64"\n",
ElapsedMicroseconds.QuadPart);
printf("Elapsed seconds : %f\n", ElapsedSeconds);
printf("rc : %d\n", rc);
return 0;
}
***** End of code *****
It would be interesting to known time on your XP boxes.
