So with Java 7u51, when I try to download a file (going through an S170 running 7.5.0) I get transfer speed of about 100 KB/sec on a 50Mb circuit, which means that the 30 MB test file I'm downloading takes 15-20 minutes... really slow.
However, when I uninstall Java, the file downloads in 1-2 seconds. Has anyone seen this behavior before? Any way to fix this? We need Java for some business applications.
