I am setting up the spring-data-gemfire in my project at my workplace. However, it takes a long time to connect to a GemFire server and retrieve the data from my application.
2020-Mar-13 09:00:10 | TRACE | annotation.ScheduledAnnotationPostProcessor | No @Scheduled annotations found on bean class: class org.springframework.gemfire.client.CLientCacheFactoryBean
2020-Mar-13 09:00:10 | TRACE | support.DefaultListableBeanFactory |Finished creating instance of bean 'gemfireCache'
2020-Mar-13 09:00:42 | TRACE | internal.ClassPathLoader | getResource(gemfire.properties)

2020-Mar-13 09:00:42 | TRACE | internal.ClassPathLoader | getResource trying: java.net.Launcher$AppClassLoader@73d16e93
.....
May I know why it takes more than 40 secs from "Finished creating instance of bean.." to "getResource.." ?
Current Versions
2.2.1.RELEASE2.2.1.RELEASEWhen i try a simple gemfire application at my home, it took around 5 seconds.

In some cases it may simply be that you're having DNS lookup issues - especially since performance seems to be different between your home and other location(s).
You can try this:
Get your hostname using the hostname command.
Add this as an alias to your /etc/hosts file for 127.0.0.1. For example if your hostname looks something like foobar.local then your /etc/hosts should be adjusted to include this:
127.0.0.1 localhost foobar foobar.local
Notice that I added both the FQDN (including .local as returned by hostname) as well as the shorter version.
