[cobalt-users] RaQ1 vs. RaQ3

[chris <chris@xxxxxxxxxxx>]

interseting: we had a RaQ1 with 128 meg RAM. The RaQ1 is a 150MHz MIPS
processor. 60 sites on the box, but a site with 3 gigabytes traffic
daily; no perl scripts. The load on the box was usually from 2 to 6.
Speed was still excellent. We were rebooting the server once every month
(no swapping at all)

httpd.conf:

MinSpareServers 50
MaxSpareServers 50
StartServers 50
MaxClients 150
MaxRequestsPerChild 63

We decided to move the site on its own RaQ3, with 256 meg RAM. The
traffic is the same, 3 gig daily, but the server starts swapping (with
256 meg RAM!) afetr 3 days and the CPU load is about the same as on the
RaQ1, maybe a little higher. We shall have to reboot the server twice a
week to avoid too much swapping, or to drastically lower the MaxRequestsPerChild

httpd.conf:

MinSpareServers 50
MaxSpareServers 50
StartServers 50
MaxClients 150
MaxRequestsPerChild 31

This site is eating the 150 simultaneous connections allowed by httpd.conf

Conclusion: the speed improvement is certainly not obvious and the
memory management seems less efficient on a RaQ3 than on a RaQ1.
