AppSignal is a performance-monitoring and error-tracking tool. It helps developers identify and solve performance issues, track errors, and gain insights into the health and performance of their Ruby applications. To use AppSignal to monitor and solve performance issues in a Ruby application, follow these steps: Sign Up and Install AppSignal: First, sign up for an AppSignal…

Use Compression: Compress the payload using techniques like gzip or Brotli. This reduces the data size and speeds up transmission. Limit Response Size: Only include essential data in the response. Avoid sending unnecessary fields to reduce the payload size. Use Pagination: Implement pagination for large datasets. This way, clients can request only a subset of…

If your application relies on external services or APIs, slow responses from those services can impact your application’s performance. Handling large amounts of data can slow down the application. Make sure to use pagination or limit the data retrieval to what is necessary.

In addition to the techniques that were already mentioned earlier in this article, there are other optimizations that can be done to solve slow queries. Batch Processing: If you have a large dataset, consider breaking your queries into smaller batches to reduce the load on the database. Use Database Transactions: Wrap multiple database operations in…

The Memory Profiler gem is an effective way of tracking the memory usage of ruby code. If you have memory leaks despite handling memory correctly, the memory allocator methods may be the culprit. Ruby typically utilizes malloc calls for memory allocation, freeing, and reallocation, as mentioned earlier. An alternative implementation of these methods is jemalloc, developed by…

The Ruby Garbage Collector (GC) module serves as an interface to Ruby’s mark and sweep garbage collection mechanism. Runtime garbage collection significantly influences memory management and recycling. Although the GC operates automatically in the background as needed, the GC module allows you to manually invoke the GC when necessary and gain insights into the progress…

Ruby’s garbage collector should automatically clean up unused objects, but memory leaks can occur if objects are not properly deallocated. Frequent garbage collection can lead to slower execution times. Here you can learn more how to track memory leaks. Memory leaks can be very unproductive and difficult to fix, and you will probably spend more time…

By using these solutions, you can avoid N+1 queries and improve the performance of your application when dealing with associated data. So, N+1 queries have been a consideration and concern in Ruby on Rails applications for many versions, and the best practices to avoid them have been part of the Rails development community’s guidelines. Always…

In the context of database queries, an N+1 query is a situation where, when retrieving a list of records (N), each record triggers an additional query (+1) to the database for related data. This can lead to performance issues as the number of queries increases with the number of records retrieved, resulting in an inefficient…

I strongly suggest measuring your application’s performance before you change anything and then again after each change. Optimize Ruby code; use the built-in classes and methods when available rather than developing your own. Reduce nested if/else, loops, and hashes if possible; all of these operations are really expensive, and sometimes just refactoring your code can…
