memcached features and specs

  • High Performance
    Memcached is incredibly fast and efficient at caching data in memory, enabling quick data retrieval and reducing the load on databases. Its in-memory nature significantly reduces latency.
  • Scalability
    Memcached can be easily scaled horizontally by adding more nodes to the caching cluster. This allows it to handle increased loads and large datasets without performance degradation.
  • Simplicity
    Memcached has a simple design and API, making it easy to implement and use. Developers can quickly integrate it into their applications without a steep learning curve.
  • Open Source
    Memcached is free and open-source software, which means it can be used and modified without any licensing fees. This makes it a cost-effective solution for caching.
  • Language Agnostic
    Memcached supports multiple programming languages through various client libraries, making it versatile and suitable for use in diverse tech stacks.

Possible disadvantages of memcached

  • Data Volatility
    Memcached stores data in RAM, so all cached data is lost if the server is restarted or crashes. This makes it unsuitable for storing critical or persistent data.
  • Limited Data Types
    Memcached primarily supports simple key-value pairs. It lacks the rich data types and more complex structures supported by some other caching solutions like Redis.
  • No Persistence
    Memcached does not offer any data persistence features. It cannot save data to disk, so all information is ephemeral and will be lost on system reset.
  • Size Limitation
    Memcached has a memory limit for each instance, thus, large-scale applications may need to manage multiple instances and ensure data is properly distributed.
  • Security
    Memcached does not provide built-in security features such as authentication or encryption. This can be a concern in environments where data privacy and security are critical.

Caddy features and specs

  • Automatic HTTPS
    Caddy automatically handles HTTPS by obtaining and renewing certificates from Let's Encrypt, simplifying the process of securing web applications.
  • Ease of Configuration
    Caddy uses a straightforward configuration file (Caddyfile) that is easier to write and understand compared to other web servers like Nginx or Apache.
  • Cross-Platform
    Caddy is designed to run efficiently on virtually any platform, including Windows, macOS, Linux, and Docker, giving it great flexibility for deployment.
  • Built-in Reverse Proxy
    Caddy includes built-in support for reverse proxy functionality, which can easily be configured to distribute load among multiple servers.
  • Extensible
    Caddy supports plugins for additional features, allowing users to extend its functionality without compromising its core simplicity.
  • Integrated Logging and Metrics
    Caddy includes integrated logging and monitoring capabilities, which make it easier to maintain and debug the server without additional tools.
  • Active Community and Support
    Caddy has an active community and is well-supported with extensive documentation, which helps new users get up to speed quickly and troubleshoot issues effectively.

Possible disadvantages of Caddy

  • Memory Usage
    Caddy can have higher memory usage compared to other web servers like Nginx, which might be a concern for resource-constrained environments.
  • TLS Configuration Complexity
    While Caddy handles basic HTTPS automatically, advanced TLS configurations can be more complicated to manage and may require a deeper understanding.
  • Learning Curve for New Features
    As Caddy rapidly evolves and adds new features, there can be a learning curve associated with keeping up to date on the latest changes and functionalities.
  • Performance
    Although Caddy performs adequately for many use cases, it may not match the high performance of optimized setups with other web servers like Nginx in highly demanding environments.
  • Licensing Costs
    While Caddy is open source, certain features are available under a commercial license. Organizations may incur additional costs for enterprise-grade functionality.

I donรขย€ย™t see any source of how the test where run, specs of the systems, how the DB where set up, etc. Would be very valuable to have in order to attempt to re-validate these test on our own platform.

Memcached vs Redis - More Different Than You Would Expect
So knowing how the difference between Redis and memcached in-memory usage, lets see what this means. Memcached slabs once assigned never change their size. This means it is possible to poison your memcached cluster and really waste memory. If you load your empty memcached cluster with lots of 1 MB items, then all of the slabs will be allocated to that size. Adding a 80 KB...
Redis vs. Memcached: In-Memory Data Storageย Systems
Memcached itself does not support distributed mode. You can only achieve the distributed storage of Memcached on the client side through distributed algorithms such as Consistent Hash. The figure below demonstrates the distributed storage implementation schema of Memcached. Before the client side sends data to the Memcached cluster, it first calculates the target node of the...

Why Redis beats Memcached for caching
Both Memcached and Redis are mature and hugely popular open source projects. Memcached was originally developed by Brad Fitzpatrick in 2003 for the LiveJournal website. Since then, Memcached has been rewritten in C (the original implementation was in Perl) and put in the public domain, where it has become a cornerstone of modern Web applications. Current development of...

  • Redis vs. Memcached: How to Choose Your NoSQL Champion
    Memcached has a single, focused goal: to be a high-performance, distributed, in-memory object caching system. It stores all data in RAM, which means reads and writes are incredibly fast. But its main weakness is just as clear: data is completely lost when the service restarts, as it offers no persistence. Its data model is a simple key-value store, limited to basic get, set, and delete operations. - Source: dev.to / 12 months ago
  • MySQL Performance Tuning Techniques
    Memcached can help when lightning-fast performance is needed. These tools store frequently accessed data, such as session details, API responses, or product prices, in RAM. This reduces the laid on your primary database, so you can deliver microsecond response times. - Source: dev.to / over 1 year ago

  • Outgrowing Postgres: Handling increased user concurrency
    A caching layer using popular in-memory databases like Redis or Memcached can go a long way in addressing Postgres connection overload issues by being able to handle a much larger concurrent request load. Adding a cache lets you serve frequent reads from memory instead, taking pressure off Postgres. - Source: dev.to / over 1 year ago
  • API Caching: Techniques for Better Performance
    Memcached โ€” Free and well-known for its simplicity, Memcached is a distributed and powerful memory object caching system. It uses key-value pairs to store small data chunks from database calls, API calls, and page rendering. It is available on Windows. Strings are the only supported data type. Its client-server architecture distributes the cache logic, with half of the logic implemented on the server and the other... - Source: dev.to / almost 2 years ago
