Python is faster every day (some of my stuff runs 400% faster, and in a few revs I’ll migrate this site to it).
Update: Decided to do it, on a whim, since the Linux binaries are self-contained and it’s trivial to switch back and forth. Yaki runs like greased lightning on PyPy, and so far everything seems to work fine without a single tweak to the code. There is a price to pay, though, which is that the measly (peak) 80MB of RAM a full (cache enabled) instance used to occupy has ballooned to 300MB while indexing content.
The main benefit so far seems to be extremely fast content indexing, full-text search (across 6K unique pages, I get instant search results) and page rendering. But with all the caching I employ, those are hardly visible to end users, so I’ll likely switch back when I need the RAM.
On a Mac, I’m getting pretty impressive turnaround times for some of my data munging. Gonna be a fun Summer.
