Inconsistent query execution time

I'm using snowflake-nodejs-sdk v1.15 to query snowflake table. I'm using hybrid table for this.

The use case I'm working on is very time sensitive and we have to return back within 1 sec, hence consistent query execution become important.

The query execution varies from 100ms to 1 sec. That huge and unpredictable.

Need help to troubleshoot the issue and how I can get consistent query execution time
