Production Problems We Diagnose

We trace difficult symptoms through application code, the JVM, JDBC, transactions, and the database.

Slow or Unpredictable Requests

Finding the cause of latency spikes, long-tail response times, and throughput collapse under load.

High CPU & Infrastructure Cost

Finding hot paths, allocation pressure, retries, contention, and wasted work that drive compute demand.

Memory Growth & GC Pressure

Diagnosing leaks, retained objects, excessive allocation, long pauses, and collectors that cannot keep pace.

Database & Transaction Bottlenecks

JDBC connection exhaustion, long-running or open transactions, lock waits, slow queries, and database-side resource pressure.

Concurrency & Resource Contention

Blocked threads, deadlocks, lock contention, overloaded executors, and shared-resource bottlenecks.

Performance Problems That Resist Reproduction

Explaining failures that resist reproduction, cross system boundaries, or disappear during conventional profiling.

About PVR Labs

PVR Labs is a boutique software lab focused on Java performance, systems engineering, and practical developer tools. Founded and led by Ted Kupolov, PVR Labs draws on engineering experience at Google, Apple, and ServiceNow, including work with large-scale production Java and database systems.

That production engineering experience underpins PVR Labs’ work in JVM performance and troubleshooting. Ted is also the creator of Scriptella ETL, and continues hands-on product development through AI Badger and StatLite.

Located in the San Diego area and serving clients globally, we help teams make complex software faster, clearer, and easier to work with.
