Java front end xhr download response time is long

background: spring
Front end: xhr
I would like to ask you, my background interface uses streaming to write a file to download (read the file out and stream it back with response), and the front end uses xhr to download the file, and the interface can link and download normally. However, why does it take a long time for some computers to download pendding before download, some seconds start to download, test environment, local area network, server tomcat, browser Chrome, clear the cache, server default configuration
