Looks like you are doing some work on goliath. I’m now getting much better numbers. Not as good as tiff but much better than before. In the 1.5 second range vs. 4.5 before. Some of that may be connection overhead and the 100mbit connection (vs gb) network speed.<BR>

I have upgraded GDAL to 1.6 "svn" to incorporate the fix for oracle<BR>
georaster overviews on the goliath server. Let me know if performance<BR>
of georaster overviews is still bad.<BR>
<BR>
Best regards,<BR>
