Browsers will cache tools popular among vocal, leading-edge developers. There's plenty of space for caching most popular frameworks. The best available proxy data also suggests that shared caches would have a minimal positive effect on performance. Suppose a user has only downloaded part of the cache.

Effective management of memory stores with policies like LRU/LFU proactive monitoring of the replication process and advanced metrics such as cache hit ratio and persistence indicators are crucial for ensuring data integrity and optimizing Redis’s performance. Cache Hit Ratio The cache hit ratio represents the efficiency of cache usage.

When you want to know if a key is present or not in the list, you run it through the hash function and check if the corresponding bits in the bitmap are “1” or “0” If one of the bits is “0”, you know for sure the key is not in the list. If all the bits are “1”, the value may be present.

It connects to PostgreSQL as a predefined user (whose password must be present in the userslist.txt file) and executes the auth-query to find the user’s password and matches it to the provided value. Once the authentication succeeds: PgBouncer checks for a cached connection, with the same username+database combination. And that is it!

On top of this foundation, we add layers of caching, prerendering and edge delivery optimizations — not the other way around. Surveying the existing landscape of available developer tools and runtimes, we felt that there is a gap. Stay tuned for more in 2022! Large preview ). Large preview ). Curious to give it a try?

The main objective of this post is to share my experience over the past years tuning MongoDB and centralize the diverse sources that I crossed in this journey in a unique place. There is an issue with this, which causes the OS to swap even with memory available. Spoiler alert: This post focuses on MongoDB 3.6.X 25.84 - Total 21.04

The cache hit was very low (a topic for another day), and whenever the server had to provide a fresh version of the page, it was taking an unacceptably long time more often than not. Synthetic tests, even properly tuned to match device and network characteristics, only occasionally surfaced the issue.
