Saya akan posting satu persatu sekalian berdiskusi mengenai tune up yang dapat dilakukan terhadap Zimbra. Saya mulai dari yang termudah, yaitu disable service yang tidak diperlukan :
http://wiki.zimbra.com/index.php?title=Performance_Tuning_Guidelines_for_Large_Deployments Linux distributions tend to enable services by default that are not really required in a production ZCS server. We recommend identifying and disabling such services to reduce risk of exposure to vulnerabilities in services that are enabled but not really needed/used, and to avoid any unintended performance interference. * Use chkconfig --list to get information about services on your system at various boot/run levels. * Examine the output of ps -ef and make sure there are no processes running that shouldn't be. The table below lists a few examples of services that may be installed by your Linux distribution that you might consider disabling. Use it as a guide - it is not an exhaustive or prescriptive list. Some services maybe required for the proper functioning of your system, so exercise caution when disabling services. * autofs, netfs: Services that make remote filesystem available. * cups: Print services. * xinetd, vsftpd: UNIX services (eg, telnet) that may not be required. * nfs, smb, nfslock: Services that export local filesystems to remote hosts. * portmap, rpcsvcgssd, rpcgssd, rpcidmapd: UNIX RPC services usually used in conjunction with network file systems. * dovecot, cyrus-imapd, sendmail, exim, postfix, ldap: Duplicates installed by the distro of functionality or packages provided by ZCS. Disable slocate/updatedb. ZCS stores one message per file, and an updatedb crawl every day at 4am can be expensive. -- Best Regards, Masim "Vavai" Sugianto /************************************************************/ Blog (ID) : http://www.vavai.com/blog Blog (EN) : http://www.vavai.net Community : http://www.opensuse.or.id Commercial : http://toko.vavai.biz /************************************************************/ ______________________________________________ --- Info Milis : http://opensuse.or.id/milis Keluar dari Milis : Kirim email ke [email protected] Manajemen Keanggotaan : http://lists.opensuse-id.org/listinfo.cgi/milis-opensuse-id.org
