Hi, Almost all people will suggest me to turn off those unnecessnary services after installation, but what kind of services should be considered as "uncessnary"? After doing some study, I list what I think about the services and hopefully someone can kindly correct my comments :) ---- 1.acpid,apmd Power Management Service. If this computer is a desktop = turn off (assume we have a UPS) if this is a laptop, keep it 2.cpuspeed Adjust CPU speed, those PC with speed-adjustable CPUs should have it. (Usually installed on a laptop?) 3.dc_client, dc_Server Should be turned on if PC is one of multiple web servers with SSL 4.Irqbalance Should be enabled if you have multiple processors. 5.mdmonitor,mdmpd Should be turned on if you have a software disk array. 6.messagebus if this pc had installed KDE/GNOME... 7.microcode_ctl if your processor is pentium-class and higher(Pentium 60-200 is not included). AMD,Cyrix,VIA and those 64-bit processors are not included either) 8.netplugd if you don't like your FC2 configure your network automatically after network is restored, you can have this service disabled. 9.random Used to generate random numbers...leave it alone? A.rawdevices Used for SCSI or some special purpose application, like Datbase Server? Don't know :( B.readahead, readahead_early Those two services can help FC2 improve its performance by load some program in advance. C.services? Don't know whtat this means... D.sgi_fam SGI's File alteration monitor Help some applications to notify user or other programs about the changes.Maybe disabled if your pc is a text_based server??? ------- Thanks for any suggestions... Patrick
