I''m running ubuntu hardy 8.04 with mod_rails on a site that gets about
1000 hits a day. the site runs perfectly fine if there are only a
handful of users making request. but when the site gets busy i run out
of memory because of too many passenger processes.
i have 256MB RAM and 512 swap.
i have tuned down some of the apache settings:
Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5
<IfModule mpm_prefork_module>
StartServers 3
MinSpareServers 3
MaxSpareServers 3
MaxClients 50
MaxRequestsPerChild 0
</IfModule>
<IfModule mpm_worker_module>
StartServers 3
MaxClients 50
MinSpareThreads 3
MaxSpareThreads 3
ThreadsPerChild 10
</IfModule>
i''m not sure what i should do next. maybe i should switch to a mongrel
cluster? are there any settings in in passenger i should be looking at
to optimize this configuration?
i don''t mind if the site slows down a little bit i just don''t
want it
crashing everyday! please help!

reading through the mod_rails help i see i can change a few parameters #define DEFAULT_LOG_LEVEL 0 #define DEFAULT_MAX_POOL_SIZE 2 #define DEFAULT_POOL_IDLE_TIME 300 #define DEFAULT_MAX_INSTANCES_PER_APP 0 i found these located in Configuration.cpp. do i need to recompile passenger? or can i just set this as a global value somewhere like in the virtual host declaration? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
