[thredds] TDS performance and NetCDF file size

Hello, I'm was wondering if there is a rule of thumb on NetCDF file sizes in 
TDS? I'm building a catalog of regional model data and I'm faced with the 
decision of structuring my files as one variable/file or all variables/file. 
The all in one approach would likely create files between 5-10Gb in the worse 
case scenario. Are there any performance drawbacks with large files, 
specifically WMS and NetcdfSubset? Are there any upper limits on file size 
NetcdfSubset can create? I saw there were some large file size problems last 
May using HTTPServer, but I expect to primarily use NetcdfSubset so users can 
cherry pick the variables they're interested in.
