Disk optimization

[Wilson Ng]

Panther has on the fly disk defragmentation.

Read here:


http://www.kernelthread.com/mac/apme/optimizations/

The relevant quote from that article is:


> 5. On-the-fly Defragmentation
> 
> When a file is opened on an HFS Plus volume, the following conditions are
> tested
> ?      If the file is less than 20 MB in size
> ?     If the file is not already busy
> ?     If the file is not read-only
> ?     If the file has more than eight extents
> ?     If the system has been up for at least three minutes
> 
> I all of the above conditions are satisfied, the file is relocated -- it is
> defragmented on-the-fly.
> 
> File contiguity (regardless of file size) is promoted in general as a
> consequence of the extent-based allocation policy in HF  Plus, which also
> delays actual allocation. Refer to Fragmentation In HFS Plus Volumes for more
> details.

For more control, TechTool Pro 4 from http://www.micromat.com/ includes disk
optimization:

> TechTool Pro 4 now offers a new optimization feature for your Mac OS X drive.
> The Mac OS X system contains thousands of files that fragment quickly.
> TechTool Pro 4 lets you quickly and safely unfragment these and other files so
> your system runs reliably at its peak

It's well worth the price. Norton Utilities for OS X has been discontinued
so I wouldn't look into that as an avenue to explore.
