I've been running Fedora on my old Thinkpad A22p (P-III/M w/512MB) since
FC4 or before, upgrading from one version to the next using the same
partition sizes. For F13 I increased the size of /boot, but kept swap at
1GB:
# fdisk -l /dev/sda
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000304c6
Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 14463 115658752 83 Linux
/dev/sda3 14463 14594 1048576 82 Linux swap /
Solaris
The last couple of releases have run agonizingly slowly with very high
load averages (between 2.x and 10.x).
I just read
http://docs.fedoraproject.org/en-US/Fedora/13/html/Installation_Guide/s2-diskpartrecommend-x86.html
which recommends a minimum of 2GB swap size for memory sizes up to 4GB.
I've been using 2x RAM for swap size ever since the 2.6 kernel was
introduced. At the moment (running 'yumex') 'top' indicates:
top - 10:43:15 up 2 days, 6 min, 5 users, load average: 8.62, 6.84,
6.26
Tasks: 244 total, 7 running, 237 sleeping, 0 stopped, 0 zombie
Cpu(s): 60.7%us, 23.5%sy, 9.2%ni, 0.0%id, 0.0%wa, 5.4%hi, 1.3%si,
0.0%st
Mem: 509800k total, 502624k used, 7176k free, 16280k buffers
Swap: 1048568k total, 317372k used, 731196k free, 101944k cached
This indicates only about 30% of my 1GB swap is being used. Would
increasing that to 2GB have any affect on the load average performance?
