Hi Ed & James

Consider it a single data point, but one that represents a number of tests, including compiling with both opendap and nco, and testing nco via both local

files and opendap-mediated access.

Altho I haven't yet run it thru valgrind, it looks like it links with nco and opendap much like the 3.6 series and seems to have the same functionality. It

does not seem to have any explosive memory leaks ;).

The netcdf4.0-linked code passes all the local file benchmarks equally as well

as the code linked to netcdf 3.6.0 and works at least as well on the

OpenDAP-retrieved data. BY that, I'm testing it vs a system equally remote to the DAP server (the server is linked against the netcdf 3.6 lib), but with

code built with the netcdf 3.6 libs.

Neither works perfectly (seemingly due to latency and timeout issues - still have to debug this. If the nco benchmark code is run on the same machine as the server, it runs to completion just fine, if slower than accessing the local files, as you might guess), but the netcdf4.0-linked code gets further

thru the benchmarks.

Great news. What is the time frame for 4.0 beta?
