            QuestDB has microsecond resolution timestamp natively. Date.now() creates a millisecond-resolution timestamp.

            If you don't mind the loss of precision, you can just multiply by 1000:

            SQLite has a checkpoint that is managed data to write data in the main memory.

            An automatic checkpoint is taken when the transaction log file becomes bigger than X GB since the last checkpoint. And after that size of the transaction log data write-in to main memory from RAM.

            Data also write in the main memory when the last database connection on a database file closes.

            How do you detect when the second transaction "starts" - is it when your first operation in it is resolved?

            Anyhow, there might be several reasons for this. One is if you have another readonly transaction going on that blocks the next transaction from finishing. Another, I suppose, could be that the background thread that handles data processing for IndexedDB may be busy with cleanup work after a transaction has finished. If that would be the case I suppose it would not happen after every run though but more sporadically.
