Minha aplicação Rocket. Chat e MeteorJs, com volume de acessos crescendo diariamente, usa MongoDB como único banco de dados. Em horários de pico o serviço simplesmente congela: todas as operações ficam bloqueadas até que o processo seja reiniciado. Já brinquei com a configuração – aumentei o cache e reduzi a taxa de novas conexões – mas o problema volta sempre que o tráfego dispara. Preciso que alguém faça um diagnóstico completo, identifique a real causa do travamento e implemente a correção definitiva. Espero uma análise minuciosa de métricas, logs, índices e do modelo de dados, além de recomendações (e execução) de ajustes que eliminem o gargalo. Se surgir a necessidade de sharding, balanceamento de carga ou tuning mais profundo, quero receber um plano claro antes da mudança. Valorizo transparência: relate cada hipótese, o que foi testado e o resultado obtido. Todo o acesso terá que ser em conjunto conosco, pois é o ambiente do cliente em produção. Entrega aceita quando: • O banco suporta o tráfego de pico sem freezes durante testes de carga. • As alterações aplicadas ficam documentadas em README ou wiki interna. • Recebo orientações de manutenção preventiva para evitar reincidência. Ferramentas que já uso e que podem ajudar: MongoDB Atlas Metrics, Mongostat, Rocket. Chat, MeteorJs APM e PM2. Sinta-se à vontade para sugerir outras. Se você domina otimização de MongoDB em ambientes de alto throughput, vamos conversar.

Hi, https://www.freelancer.com/u/mindmagic1 Imagine your Meteor app handling peak traffic seamlessly without freezes. I’ll start by performing a full diagnostic: analyzing MongoDB metrics, logs, indexes, and data models, and reviewing your Meteor app’s queries and connection handling. Next, I’ll identify bottlenecks, test adjustments, and propose solutions—whether index optimization, query refactoring, caching strategies, or sharding and load balancing if necessary. Finally, I’ll implement approved changes, document all modifications, and provide maintenance guidelines so your database stays performant under high load. Your app will remain stable even during traffic spikes.

Greetings, I've read through your project, and it sounds like you're dealing with some frustrating MongoDB performance issues during peak traffic times. I can see how important it is for your Meteor application to run smoothly, especially as user demand grows. My plan would involve a thorough analysis of your current setup, including metrics, logs, and data models, to pinpoint the cause of the freezes. I will take a close look at your MongoDB configurations, test various adjustments, and if necessary, present a clear plan for implementing solutions like sharding or load balancing. Transparency is key for me, so I'll keep you updated on every step and document any changes made for your internal records. With my experience in optimizing MongoDB for high-throughput environments, I’m confident we can eliminate these bottlenecks together. Best regards, Mehran Riaz

Hi there. I have over 10 years of experience in this tech field. I understand your Meteor service freezes when MongoDB traffic peaks, which usually indicates lock contention, slow reactive queries, or connection pool exhaustion. In a fintech platform I fixed similar freezes by analyzing MongoDB Atlas Metrics, mongostat, and Meteor APM traces to locate blocking queries and oplog lag. I then rebuilt indexes, optimized publications, and tuned WiredTiger cache and connection pools. After load tests the system handled peak traffic stabley without restarts. I will review logs, metrics, and query plans with your team and test each hypothesis transparently. One question: do freezes coincide with write spikes or subscription bursts? If you entrust me with this project, I guarantee the best results. Skill is important, but I think the collaborative spirit of a freelancer is fundamental. If you hire me, I will do my best until you are completely satisfied. Best Regards. From zlatko
