Poor performance in .NET 9 compared to .NET Framework 4.8 issuing queries #640
Description
I am seeing far worse performance when issuing queries in .NET 9 when compared to .NET Framework 4.8. In both frameworks the first query I issue takes about 1 second to execute. But in .NET Framework subsequent queries using the connection take a fraction of a second whereas in .NET 9 each subsequent query also takes about 1 second to execute.
I've created a video here that exhibits the problem in it's simplest terms: https://1drv.ms/v/c/43cb1d1838b1f8ea/ETljxLEcDX9AievnCxj6PiQBIndhgdTFtuM4fAmNuBmr0Q
I am running against SOLR 9.5.0. We are converting our project to .NET 9 from .NET Framework 4.8 and this is a pretty major performance regression for us. Any assistance would be appreciated. I suspect that .NET 9's implementation is disconnecting and reconnecting with each query whereas in the .NET FW implementation it is reusing the already connected connection object.
