Dear David, All<br>
<br>
I am now using VNC and got my scripts to do non-interactive viz, i.e.<br>
making of png files using the script below. However, I have a question<br>
regarding efficiency of the run.<br>
<br>
As of now, I am doing a serial run. The first several png files are produced<br>
swiftly. However, eventually, the run slows down considerably.<br>
e.g. files 1 to 200 are at a rate of 10 per second <br>
but files 300 to 35 are almost 1 every 2 minutes.#<br>
<br>
Any ideas why this is, and how to rectify this? Isthis a memory leak and if so<br>
how not do introduce this when making the .py script using the trace option<br>
in the GUI?<br>
<br>
cheers<br>
Sanjay<br>
