I am resending this but differently We would like to know how to performance tune Red Hat. We are only using this for Email (Cyrus, Postfix, OpenLDAP, Apache, ProFTPD). Any ideas what could be turned off and/or where to point me to performance tune this puppy so that it works at its very best as an email server.
Here is my chkconfig --list:
I would turn off the following items as well as removing their assocatiated rpm installation.
gpm netfs irda nscd (this one is variable, I probably would install bind and caching-nameserver rather than this)\ isdn ip6tables (unless you are doing ipv6 iptables rulesets) pcmcia sendmail autofs portmap nfs nfslock snmptrapd rhnsd cups ypbind snmpd (unless you need snmp for metrics) vncserver hpoj winbind lisa smb dc_client (don't know what this is) dc_server (don't know what this is) httpd squid dhcrelay vsftpd dhcpdtux netdump-server yppasswdd ypserv ypxfrd dsanet (don't know what this is) dkms_autoinstaller (don't know what this is) procfgd (don't know what this is) tomcat kadmin (don't know what this is) kprop (don't know what this is) krb524 (don't know what this is) krb5kdc (don't know what this is) spamass-milter mdmpd insightserver (don't know what this is) clamav-milter sgi_fam: krb5-telnet:
