Default OOcalc plotting performance issue

I'm having some pretty severe performance problems with OpenOffice

Here's the environment:

Intel 2.67 GHz P4 (yes it's underpowered, but see below)
NVidia 7600 GS over-clocked with 260.19.36 binary driver
1.5 GB memory
Fedora 14 latest patches

The applications:

OpenOffice Calc 3.3.0-20.2
Gnumeric 1.10.12-1
KSpread 2.2.2-4
Sun JRE 1.6.0_22 (instead of 1.6.0_23 to work around tmpdir bug)

The plot:

Size: 8700 points
Plot: XY scatter, points and lines, no smoothing

The problem:

Increasing the horizontal size of the graph takes approximately 10
minutes. During this time the CPU is at 100% and the mouse cursor
remains as a double-headed arrow, preventing interaction with the
rest of the desktop. This occurs regardless of windowing system (KDE,
Gnome, WindowManager).

Decreasing the horizontal size works reasonably well (about 10

A bit more detail:

Fedora 14
OO 3 / JRE 1.6.0_22 vertical increase size - 10 seconds
horizontal increase size - 600 seconds
gnumeric vertical increase size - 2 seconds
horizontal increase size - 6 seconds
kspread segmentation fault creating graph

XP/Professional (same hardware)
00 3 / JRE 1.6.0_23 vertical increase size - 5 seconds
horizontal increase size - 30 seconds
Excel 2000 vertical increase size - 1 second
horizontal increase size - 2 seconds

Are other people experiencing similar relative performance issues? If
this is not an artifact, where should it be reported?

Yes, I can use some Perl scripts and gnuplot as workarounds.

. . . . just my two cents
