MySQL & ADO queries speed

Hi,

why the speed is so low ~ 12 queries per sec.?

I'm uploading ~ 5000 records doing sequential calls of ADODB.Command's Execute from this snippet.

Yes, I'm re-using the existing connection (oConnect object above).
Yes, I have good internet upload speed & ping.

Is it due to Sync call? Does ADO have Async alternative?

Or should I pack everything in a transaction?

Thanks.
