Atualmente, estou executando um site em dois locais diferentes (datacenters), mas executando a mesma máquina. Nos últimos meses, todo o desempenho foi degradante e não consegui encontrar um culpado.
Ambas as máquinas estão executando a CPU Intel (R) Xeon (R) E3-1245 V2 @ 3.40GHz (8 threads), 32GB de RAM, discos SSD de 2x120GB no SoftRaid.
Ambas as máquinas estão executando o seguinte software:
- php-fpm7.1
- nginx
- Percona MySQL (configurado como master-master)
- Redis
Ambos os servidores estão executando o mesmo código e estou usando o Amazon Route 53 para equilibrar o tráfego usando o DNS.
Os servidores costumavam rodar bem com ~ 2000 usuários navegando pelo site (dados do Google Analytics), com médias de carga nunca ultrapassando 1.
Recentemente, tenho visto um enorme desempenho degradado. Qualquer tarefa aumentará a carga média para 6-8 e, às vezes, ultrapassa 15-20 facilmente. Até mesmo uma única implementação de código (algumas tarefas bash e um clone git sem muita complicação) demorará uma eternidade e verá a média da carga aumentando e desacelerando a máquina inteira e o site.
Alguns meses atrás, tive que aumentar as conexões do MySQL e, ao mesmo tempo, aumentar o limite de arquivos abertos. As conexões atuais do MySQL são em 2000 e eu deixo o MySQL abrir os arquivos por si mesmo (value = 0 irá detectar isso automaticamente para você).
Meu principal palpite é que é algo relacionado à configuração do banco de dados, vejo lentidão durante a replicação (é uma replicação master-master) e toda vez que há uma inserção no site eu posso ver os tempos de carregamento saltando para 10-15sec .
O mais estranho é que eu só tenho tráfego em um servidor. Com o AWS Route 53, eu removi um dos servidores do pool para que apenas um dos servidores esteja recebendo carga e, mesmo assim, a máquina está sobrecarregada. Aqui está um exemplo:
Enquantoissoacontecia,tenteifazerumcomentárionositequeéumsimplesINSERTparaumatabelaondeexiste1linhaeapenasinsere3valores:
A coisa é ... este site funciona melhor na minha máquina de desenvolvimento Vagrant com 1 CPU e 2GB do que ele está fazendo realmente em produção com caixas enormes.
Tenho certeza de que há arquivos que você gostaria de ver para ajudar, mas eu não sei o que poderia ser útil, então me avise e mostrarei qualquer configuração que você possa precisar.
Obrigado antecipadamente!
