Hi After migration from squid 3.3.13 to 3.4.4, I recognized a performance-issue. Squid is configured with 4 workers. They often have a CPU-Utilization between 50%-90% (each worker). With squid 3.3.13 (same configuration), the CPU-Utilization was never a problem. I installed squid 3.4.9 and had the same issue. No warnings/errors in the cache.log I saw, that someone other reported a similar issue: http://www.squid-cache.org/mail-archive/squid-users/201407/0500.html Concerning the post above: Yes, we have external_auth-helpers (ext_kerberos_ldap_group_acl) and no, we do not use delay_pools. The high cpu-usage comes not from the auth-helper - it comes from the 4 squid-worker-processes. Any hints? Is this a known problem? Probably solved in 3.5?
