[give up]Very slow SATA drive performance in Arch

Hi everybody!
My laptop is HP 6715S with RS690 chipset,1.5G memory.I have to spend about 4 minutes to fully boot up into KDE by use startx.
Can some one help what could be the reason?Is there any way to improve sata performance under Arch?

/dev/sda:
setting using_dma to 1 (on)

What chipset does your machine use?

I'd not trust hdparm with SATA drives. As noted in the man page, its' primarily for use with (E)IDE drives. Try using sdparm.
