Hello.
I noticed that the sqlite code looks like below. On windows this will result
in 5 system calls instead of 1 each time the journal is made.
Why not batch it all together into a single write?
/Ludvig
rc = sqlite3OsWrite(&pPager->jfd, aJournalMagic, sizeof(aJournalMagic));
if( rc==SQLITE_OK ){
/* The nRec Field. 0xFFFFFFFF for no-sync journals. */
rc = write32bits(&pPager->jfd, pPager->noSync ? 0xffffffff : 0);
}
if( rc==SQLITE_OK ){
/* The random check-hash initialiser */
sqlite3Randomness(sizeof(pPager->cksumInit), &pPager->cksumInit);
rc = write32bits(&pPager->jfd, pPager->cksumInit);
}
if( rc==SQLITE_OK ){
/* The initial database size */
rc = write32bits(&pPager->jfd, pPager->dbSize);
}
if( rc==SQLITE_OK ){
/* The assumed sector size for this process */
rc = write32bits(&pPager->jfd, pPager->sectorSize);
}
