[Benchmarking] Re: MapServer and GDAL/GeoRaster driver

[Smith, Michael ERDC-USACE-NH]

Frank,

Looks like you are doing some work on goliath. I¹m 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.
