Slow NFS writes with sec=krb5

We just realized what is special about the two machines that are fast
regardless of the sec option: They’re still running the 3.2 Linux
kernel. All other machines have at least the 3.13 kernel.

Did they change some default configuration between 3.2 and 3.13?

Best regards,
Florian
