Hi all, I have a question regarding Solr 9.x:
After we updated to Solr 9.x, we noticed that the first get/post request on a new TCP session takes much longer compared to older versions of Solr (we tested Solr 6.x and 8.x) - but only if this first request is sent via a proxy. Without a proxy Solr9.x is as fast as the previous versions. The logging in Solr does not show anything suspicious. First, we assumed it has something to do with the embedded jetty version (got updated from jetty 9.x to 10.x in Solr 9.2) but Solr 9.0/9.1 also show this unexpected delay. Example Solr 8.11.4: Response to the first Request on a new TCP session is very fast: [cid:image001.png@01DB2BB4.DFA80600] Example Solr 9.0: Response to the first Request on a new TCP session is quite slow (5 seconds): [cid:image002.png@01DB2BB4.DFA80600] Does anyone have an idea why there is this different behaviour and where to start searching?
