[hunchentoot-devel] serious H'toot performance problem on CCL OSX ?

[Andrey Moskvitin]

I have the following situation with http://lisper.ru/ (Hunchentoot +
SBCL on Debian VPS
without Apache, nginx, etc.)

$ /usr/sbin/ab -n 100 -c 1 http://lisper.ru/

I believe that a significant decrease in performance when the number of requests
for more than 10 due to the limited resources of VPS. On my working
machine (Gentoo)
performance degradation with increasing number of requests is much smaller.
