It takes too long (about 10s) to get HTTP 404 for missing checksum files

There are artifacts in repository.jboss.org which do not have checksum files available. For example http://repository.jboss.org/nexus/content/groups/public/org/apache/maven/maven-parent/5/maven-parent-5.pom.md5 does not exist, but the artifact itself does: http://repository.jboss.org/nexus/content/groups/public/org/apache/maven/maven-parent/5/maven-parent-5.pom.

This is not ideal and it would be great if that can be fixed.

However, the real issue I ma facing is that it takes about 10s to get 404 from the server telling me the checkum file is missing. This considerably slows down Maven builds as Maven is waiting for those answers. And there is usually more that few of these missing checksum files.

wget example from my machine, but I see the same behavior in Central CI as well (note the time difference between start of the request and the answer from server - in this case 11s):

wget http://repository.jboss.org/nexus/content/groups/public/org/apache/maven/maven-parent/5/maven-parent-5.pom.md5
