Ok. Minecraft is written in java, true. You only have a gig of RAM,
that's a potential problem.
Java is infamous for wanting RAM, and lots of it, and Minecraft, due to
the size of the worlds than it generates (the engine can generate a
world that is about eight times the size of the earth), wants a /LOT/ of
memory.
Easy enough to verify: Run Activity Monitor. Set it to update less
often. Display the system memory pane. Watch the size of the
Inactive list and the page in/out rates. If the inactive list is
tiny, then you're low on RAM. If the paging rates are going nutz
(changing rapidly), then the system is slowed because it's busy
paging instead of running the game.
Also, Minecraft is still beta (not finished and potentially has
bugs), so lag, especially when playing online, is often unavoidable
and often due to the server more than the client. The minecraft
forums are
full of people having issues with lag.
How much lag and latency is tolerable in this game? If Anne's 'net
service is only 1 Mbps downstream, her upstream is apt to be horribly
low. Is there a specific server she could run some traces to?
If you spend money on anything, upgrade your RAM and perhaps look at
upgrading to 10.6, but even then, he's probably going to still have
the occasional bout of lag.
Ya.
Anne, run OnyX. Use it to run the three Apple maintenance scripts,
then clear all user, app, system, and kernel caches, then reboot.
The scripts may take a long time to run, if they haven't been run
recently. The reboot will take quite a bit longer normal, as it
rebuilds the kernel cache. Then reboot again. An alternative, after
you've run those three maintenance scripts with OnyX, is to just use
AppleJack and tell it to do everything. hum. On 3rd thought...
yea... Run those maintenance scripts then use AppleJack. It does a
deeper cleaning then the cache rebuilds, in a more wholly / easier
automated fashion.

How does OnyX differ from MacJanitor?
Last I looked, MacJanitor only ran the three maintenance scripts.
OnyX is a much more comprehensive tool. In addition to helping you
do all sorts of maintenance tasks, it will also let you tweak some
cool hidden system and application prefs.
