VIRT has always been high

I want to test the amount of concurrency of the query

I used a loop to open a coroutine of 100,000 queries at the time.

VIRT has reached 10G and will not fall after the end.

Is it normal?

The day after,
I didn’t run anything, VIRT got bigger
It is close to 11G

Are you seeing spikes in kswapd0 too? I posted about my experience at Massive kswapd0 CPU spikes?

yes,hope you find the answer soon
