I was curious as to how well blosxom would handle large numbers of articles - my main worry was whether it would slow down much if it had to sort through a lot of stories before displaying anything. The timings here are for 100,500,2000 and 10000 stories.

Times are in milliseconds and are the average of 10 runs. If the'entriescache' plugin is used then blosxom seems to manage quite well.

Notes:

1. All of the plugins removed before running the benchmarks
2. All of the plugins except for entriescache
3. entriescache using reindex=y to force reading all the files
4. entriescahce in normal use

Conclusions:
Blosxom seems to scale reasonably well with increased number of files, especially so when entriescache is installed. If a large number of stories are to be displayed, it's probably a good idea to have entriescache to only rebuild the cache when needed, by setting to a large number such as 999999 which would rebuild every approximately 2 years.
