---------------------------------------------

Esta configuración del my.cnf hizo que bajara en 2 puntos la carga del servidor que andaba desde las 20:15 hast las 20:50 entre 5 y 6. Con esta nueva configuracion del my.cnf bajó entre 2 y 4 con picos preopucantes com oel que he puesto antes

--------------------------------------------
La configuración del apache es la siguiente: (coloco lo más significativo)




RLimitMEM 292394325
RLimitCPU 240
KeepAlive On
MaxKeepAliveRequests 0
KeepAliveTimeout 5
UseCanonicalName Off

TraceEnable On
ServerSignature Off
ServerTokens Full
FileETag All
StartServers 5
<IfModule prefork.c>
MinSpareServers 10
MaxSpareServers 10
</IfModule>
MaxClients 256
MaxRequestsPerChild 500


------

ESTOS PICOS SE PRODUCEN CUANDO HAY 300 USUARIOS ONLINE A LA VEZ realizando acciones en la web.

¿que he de hacer? ¿Problema de configuracion? ¿Porblema de que el servidor no da mas de si?
