Slow queries — sound familiar?
- ▸ WiredTiger cache thrashing — Your working set exceeds
storage.wiredTiger.engineConfig.cacheSizeGB. Evictions run constantly, and every dashboard refresh sets off an IO burst. Read p99 latency jumps 10×. - ▸ Aggregation pipeline COLLSCAN — A $lookup or $match early in the pipeline can't use an index. So you scan whole collections during business hours. The oplog falls behind, and replica members block on $merge.
- ▸ Hot shard from bad shard key — A single shard holds 70%+ of the working set. The balancer can't fix that without re-sharding. Chunk migration during business hours then triggers cluster-wide latency spikes.

MongoDB Performance Tuning & Optimization Services
In short: MongoDB performance tuning is the work of making a MongoDB deployment serve its workload faster and more predictably. It covers slow-query and aggregation-pipeline optimization, compound and partial index design, WiredTiger cache and memory-allocation tuning, and sharding balance through shard-key selection and chunk distribution. The work is diagnosed with profiler and explain-plan data, then validated against before/after metrics.
Transform your MongoDB database performance with our expert NoSQL optimization services. We guarantee 70-95% faster queries. Our work also covers MongoDB aggregation pipeline optimization and comprehensive WiredTiger performance tuning services.
Common MongoDB Performance Issues
Are you experiencing these performance challenges with your MongoDB database?
Slow Query Performance
Queries and aggregation pipelines taking too long to execute, affecting user experience and application responsiveness.
High CPU Usage
MongoDB server consuming excessive CPU resources due to inefficient queries and poor indexing strategies.
Memory Issues
Inefficient memory allocation in WiredTiger cache causing frequent page faults and performance degradation.
Sharding Bottlenecks
Unbalanced shard distribution and poor shard key choices causing hotspots and performance issues.
