프로세서 확인좀 부탁드려요...

ps -ef 한 결과가 아래와 같습니다.

이번에 SULinux를 깔았는데 메모리를 너무 많이 먹고 느려진것 같아서 확인해 보니 기존에(Redhat9) 없던 events, migration, khelper, kacpid, kblockd, aio, kseriod, ata, scsi_eh, udevd, kauditd, kmirrord, irqbalance, saslauthd, [pdflush]프로세서가 있더라구요 그리고 mingetty1프로세서도 기존에는 하나만 떠있었는데 5개나 더 떠있어요. 이프로세서들의 역할과 사용하지 않으려면 어떻게 해야하는지 답변좀 부탁드려요...
