peformance bottleneck in wanna-peruse

[Chris Rutter <chris@willow.armlinux.org>]

Though this top report for while the page was being generated seems
to suggest that CPU is not a bottleneck:

30288 daemon    20  19   256  220   156 R N  83.8  0.3 944:28 distributed-net
 8228 apache     0   0  3484 3476  2352 D     7.1  5.4   0:10 apache

(Those being the top four entries.)
