<tt>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:</tt>

<tt>The last couple of releases have run agonizingly slowly with

<tt>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:</tt>
<blockquote>

<tt>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</tt>

<tt>Swap: 1048568k total, 317372k used, 731196k free, 101944k cached</tt>

<tt>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?</tt><br>

Don't run Gnome/KDE desktops - they're memory hogs. Instead, try
XFCE - it's much lighter and faster (fewer features, though).<br>
You have ~800MB of virtual memory used (mem used+swap used) with
nothing but yumex.<br>
I have Thunderbird and Firefox and several small programs open; my
virt memory usage is at ~600MB. The rest of my 2G is buffers and
caches.<br>
<tt><br>
Mem: 2061244k total, 1999948k used, 61296k free, 303296k
buffers<br>
Swap: 0k total, 0k used, 0k free, 917156k
cached<br>
</tt><br>
<br>
As far as swap, keep it at 1G, it's a reasonable setting with your
hardware.<br>
With my 2G RAM, I have the swap partition at 2G, but keep it turned
off most of the time -- the programs I open rarely, if ever, fill up
the 2G and it's faster to not use the swap when you don't need it.
But that's just me, not a recommendation of any kind :)<br>
