the speed may depend on cpu but also on where your data is stored (are your datasets available locally?) and how your script is written ...<br>
Upon my knowloedge GrADS IS fast, it may be the fastest sw you can find everywhere ...<br>

Oggetto: [gradsusr] GrADS performance vs alternatives? <br>
<br>
<br>

Hi,<br>
<br>
<br>
<br>
I've recently started generating ECMWF 50 member ensemble plots using a GrADS script for a large latitude - longitude range. Technically it all works fine, but the issue I'm having is performance. It is dependent of course on CPU speed, but even with a very fast processor each individual graph can take approx 1.5 seconds to render and save.?<br>
<br>
<br>
To an extent running instances on multiple cores helps, but generating a range of graphs (e.g. 2m temps, 850hPa temps, MSLP etc...) can take a long time. Perhaps 40 mins or so for a country the size of the United Kingdom.?<br>
<br>
<br>
Does anyone have tips for how to optimize performance in the script? Alternatively, is there software available which runs much faster than GrADS script to do the same thing??<br>
<br>
<br>
Thanks<br>
<br>
<br>
