This examination by Nelson Elhage investigates the performance of CPython's new tail-calling interpreter, finding that initial reports of 10-15% speedups were significantly inflated due to an unrelated LLVM 19 compiler regression affecting the comparison baseline. When benchmarked against properly optimized older versions or compilers, the actual performance gain attributable to the new interpreter implementation itself is more modest, typically in the 1-5% range.

This piece examines why certain Python libraries, often used for web scraping and automation, can lead to noscripts being blocked or blacklisted by cloud providers and websites due to aggressive activity detection or security policies. It discusses specific libraries like Scrapy and Selenium, explains the reasons for potential bans, and offers strategies such as request throttling, using proxies/VPNs, and randomizing behavior to avoid detection.

This recounting by Max Bernstein details a real-world performance optimization saga from developing a custom Python runtime, where a seemingly innocuous string function bottlenecked Django performance. The analysis reveals how a naive Python implementation of str.rpartition led to excessive, costly UTF-8 indexing operations, emphasizing the need to look beyond surface-level profiler results to find the true cause of slowdowns.
