Speeding Up Java Graphics (JVM)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I know this is the Fedora, not Java list; but I'm not getting any help
over there!

Speaking from a hardware standpoint, we distribute our systems on Dell
PowerEdge 1800 Server machines and we're limited (by our own hardware)
to 512MB RAM.  It stands to reason that these machines don't have very
beefy graphics support in them.  Low end nVidia or ATI chipsets at best!

We're doing some work in Java, running under Sun's JVM and driving the
graphics card with images while the CPU is at a decent load.  As our
images grow in size the drawing slows down.  The 640x480 stuff is good,
the 1280x1280 stuff is alright but the 2048x2048 is unusable.  

>From a hardware / (operating system) software standpoint, what would you
do to speed things up?  I can't add memory; we don't have any open slots
to add in another graphics card and using a workstation model machine
with better graphics isn't a choice either.

Any ideas???

TIA,
