I installed RedHat 5.0 and 5.1 on the same hardware - ALR Rev 6x6,
quad Pentium Pro, Adaptec SCSI controller on the motherboard, 4.3GB
ultrawide hard disk.
With 5.0 it takes about 15 seconds to format a 128MB swap file. With
5.1 it takes 5-10 _minutes_. Imagine how long it will take to format
my 1.6GB /home partition! Symptoms: 5.1 formats a small part of the
swap, then stops for a while, then does another small segment, etc.
During the pauses, there is no disk activity at all, and the CPU
shows about 10% utilization.
