Eu sou novo em Turpentine and Varnish, eis as minhas configurações:
nginx -> verniz -> nginx -> php5-fpm
O verniz funciona bem quando eu configuro o nginx para ouvir a porta 80 e depois encaminhar para o verniz sem usar ssl (não está executando o verniz diretamente no 80), ele funciona bem, a página em cache é rápida, o primeiro hit é um pouco mais lento (o primeiro hit cerca de 200ms, em cache) página atingiu cerca de 7 a 20 ms).
Então eu tento enrolar o verniz com https, primeiro testei com certificado autoassinado, o primeiro hit ficou lento como o inferno ( 30s + , sim, segundos, não ms), o hit em cache ainda é rápido, 7-20ms. um certificado do letsencrypt.org, mas não corrigiu o problema.
Eu não entendo direito o que está acontecendo aqui e não tenho idéia de como descobrir o que está fazendo com que seja tão lento.
editar: Não há aumento significativo no uso de RAM ou CPU durante a espera dos anos 30.

Respostas:
Provavelmente, a causa é SSL Termination ou TLS Termination Proxy .
Eu vejo sua configuração do SSL no próprio Nginx, considere usar Pound ou se você estiver usando um Load Balancer para finalizar o SSL lá em vez do Nginx.
Se você está recebendo um atraso exato de 30 segundos, provavelmente está atingindo um tempo limite:
Depois de desabilitar os endereços IP do rastreador do site, o loop local dos cookies SSL poderá ser definido corretamente e não tentar atingir o frontend.
Mais detalhes sobre a configuração do SSL para Magento + Turpentine:

é melhor que sua configuração seja de outra maneira:
envernize na frente na porta 80 e depois nginx nas portas 443 e 8000:
Ao fazer o proxy HTTPS para o verniz, é melhor adicionar esses cabeçalhos:
em seguida, no nginx: 8000 parte recebida, você deve adicionar o ip real:
caso contrário, será uma bagunça. dessa forma, o Varnish: 80 sempre captura a solicitação direta do usuário, e o nginx: 443 descriptografa o ssl para o Varnish e, em seguida, o Varnish envia a solicitação não armazenada em cache para o nginx: 8000
essa configuração é um pouco mais limpa, mas é muito difícil dizer por que você tem mais de 30 segundos.
