Issue/Introduction

Searching in Clarity slows down the application, what are the best practices to avoid heap dumps and OutOfMemory (OOM) errors?

Environment

Release: All

Resolution

• Search in Clarity is a memory-hungry operation that could consume hundreds of megabytes of memory.
• Sometimes a user gets impatient and opens multiple requests at a time. Opening a second and third tab or refreshing the page will only resend the request in at the same time. This creates another long-running concurrent request, which will not make things faster but slow them down and even can bring down the application server.
• We recommend searching in the application one request at a time, which will ensure the request will proceed at a maximum speed and will ensure the application's stability.
