Have you any progress in invetigation performance issue on squid 3.1.10 with squid_kerb_auth 1.07? Because I ran in the same situation as Simon and found that issue apear only on x64 linux. I build two identical systems on Centos 6.3 + Squid 3.1.10 with x64 and x86 system architecture. And I have to say that x86 sistem is behave adequate to its load. Kerberos libraries, squid and kerberos helper are the same version, the only difference is processor architecture.
