Polling interval

[Ajeeth]

On profiling the database, I could see many continuous hits of SQL (Selects) in the Queue table. Is this generally fine or okay? . Is there a way to control the polling duration of NGinn handlers in config files.

Thanks,

Ajeeth

Yes, each receiver thread polls the queue every 10 seconds on average (which isn't very frequent). Apart from that, all queries will hit an index so it's very cheap regarding CPU and I/O cost.

Best regards

BTW currently there's no way to set the polling frequency via config API, but if you'd like to change it for some reason I can add a property for this.
