System Wait kill MySQL/PostgreSQL performance ?



Hi,

I have a problem importing data from Flat Files
into either MySQL or PostgreSQL databases.
Importing some 6 million lines takes 
as few as 60 seconds on a fast Opteron server,
and will not finished overnight on my 1.5Ghz Centrino Laptop.
Top shows the Laptop is stuck in 9x% Wait.

I am using the bulk load mechanism of both RDBMS (load data or copy from
file). I tried disabling the db logfiles, used ext2 instead of ext3 for
their data, to no avail.

System is sarge, Kernel is a 2.6.8.1, PostgreSQL 7.4.5 and MySQL 4.0.12,
noflushd is disabled, DMA is on for hda. Is there any laptop-specific
setting done in debian which could cause the slowdown ? 

Yours,
Steffen
