Try with bigger cache size.
I think ADO uses bigger cache so it can work longer only
in memory. Transactions can help, but in case of many
updates/inserts there is not enought space in cache, so
the rows are stored on disk.

Are you doing the inserts in a transaction? That makes a big difference.

Say, are you testing inserts?

Hello Andrew,
I'm a little confused about the precompiled SQL. According to Wiki, there
should be something like sqlite_bind() that I can use. However, I can't
find sqlite_bind() in my sqlite source ...

Hello Greg,
The insert is not in transaction. I do the insert and update like
CCriticalSection cs;
void CDB::insert()
{
cs.Lock();
sqlite_exec_printf(pDB, "insert in
ese are just guesses. I'm trying to dig out why. Maybe you guys who are
more familiar with sqlite internals can show me the answer :)
