Subject Re: Re[2]: [firebird-support] How to change cpu u tilization in Firebird engine?
Not related to queries, like I said before, it was for maintenance such as backup / restore, delete, insert,etc.

From those operations, I noticed that Firebird 3.0 SS didn't use 100% cpu utilization. For queries, i guest, the behavior will be same

If cpu utilization can be set, perhaps, all operation, including queries can benefit from higher cpu performance.
