Initial impressions of HipHop PHP and porting Pressflow
I spent most of the weekend porting Pressflow to HipHop PHP. Josh Koenig from Chapter Three was also kind enough to spend much of his Saturday working with me. Pressflow doesn't quite run on HipHop yet, but we're working on it. Building HipHop PHP and Pressflow Getting a good build of HipHop was quite a challenge. However, if you're on 64-bit Ubuntu 9.10, you just have to follow our build instructions.
Intelligent memcached and APC interaction across a cluster
Anyone experienced with high-performance, scalable PHP development is familiar with APC and memcached. But used alone, they each have serious limitations: APC Advantages Low latency No need to serialize/unserialize items Scales perfectly with more web servers Disadvantages No enforced consistency across multiple web servers Cache is not shared; each web server must generate each item memcached Advantages Consistent across multiple web servers Cache is shared across all web servers; items only need to be generated once Disadvantages High latency Requires serializing/unserializing items Easily shards data across multiple web servers, but is still a big, shared cache Combining the two Traditionally, application developers simply think about consistency needs. If consistency is unnecessary (or the scope of the application is one web server), APC is great. Otherwise, memcached is the choice. There is, however, a third, hybrid option: use memcached as a coordination system for invalidation with APC as the main item cache. This functions as a loose L1/L2 cache structure. To borrow terminology from multimaster replication systems, memcached stores "tombstone" records.
