Slow 12.04 on a Netbook with LVMs

[Amichai Rotman]

Hello,

I have an Asus EeePC running 12.04.2 set up with 3 Pencrypted partitions:

One for the / (System); One for swap and one for /home

The system becomes slower and slower. I noticed that the encrypted
partitions are set up as extended (=not primary). I read somewhere that
that slows down the file access.

I want to redo the installation, and I have a few questions:


   1. Can I use an external hard drive formatted as NTFS to backup the
   files on /home (ext4)?
   2. I want to create only primary type partitions, I remember that it
   asks for an extended type partition when configuring the encryption.
   3. I'd like to create the swap space as a file, not a partition.
   4. It's a 160Gb SATA drive. I need as much space as possible for my Data
   files. What would be the best way to partition the drive?
   5. What's the best way to configure the LVMs?

Thanks!

Amichai.
