Hello all testers....
Questions of performance with GRIBs
Anyone experiencing slow performance in the following cases?
a. GRIB dialog loading, with a relatively large number (> 10 or so?) of files in the GRIB directory....
b. Chart dragging, clicking, etc. with a GRIB displayed. Any difference whether the GRIB has both wind
and pressure, or just one or the other? System config info, too, please.
We pre-read all GRIB-looking files in the chosen directory to prepare the list of forecast
valid times. As I was coding this, I suspected this may be too slow for general use, but it clearly depends upon how many files are in the directory.
If we don't pre-read the files, then we have no sure way to order them in the selection tree list, so the GRIB file you want may be very far down the list of available files. We could arrange them in order of file modification date, but this is not a sure thing. We really want to order on the basis of forecast
Today, the best performance will be gotten if the GRIB directory is kept separate and not too full of old files.
I am open to opinions here. How to parse and manage a potentially very large shoe-box folder full of GRIBs?
