Aunque no recomiendo apache para servir archivos estaticos (demasiado overhead, es mejor que le eches un ojo a nginx o a lighttpd), encontre hoy una directiva que puede eliminar un poco el overhead al hacer una llamada directa al sistema -> sendfile.<\/p>\n

De momento lo que hice en uno de los servidores fue muy sencillo:<\/p>\n

\nsudo apt-get install sendfile\n<\/pre>\n
Agregamos la directiva en \/etc\/apache2\/apache2.conf<\/p>\n
\nEnableSendFile On\n<\/pre>\n
(Puedes poner esta directiva solo en algun directorio, si lo deseas solo en un directorio)<\/p>\n
Reseteamos el servidor<\/p>\n
\nsudo kill -HUP <#proceso_principal_apache>\n<\/pre>\n
Chequeamos que no haya pasado ningun error con la configuracion<\/p>\n
\ntail -f \/var\/log\/apache2\/error.log\n\n[Tue Aug 07 08:11:30 2007] [notice] SIGHUP received.  Attempting to restart\n[Tue Aug 07 08:11:33 2007] [notice] Apache\/2.2.3 (Ubuntu) configured -- resuming normal operations\n<\/pre>\n
Supongo que ahora esta funcionando con sendfile, noto menos tiempo de espera para recibir el archivo.<\/p>\n
Si alguien tiene algo que comentar sobre EnableSendFile, bienvenido, primera vez que lo pruebo, aunque brevemente pq montamos nginex en esa maquina a los 10minutos de probar esto. \ud83d\ude41<\/p>\n","protected":false},"excerpt":{"rendered":"
