[Gnuplot-info] PNG plots very slow when gnuplot is compiled with WXT terminal

[RM07 <ma...@ve...>]

I have an application which creates small PNG plots (2K - 6K in filesize) in
pseudo-realtime.

On a non-WXT compiled gnuplot (4.2.5) these plots generate in ~100ms.

On a WXT compiled gnuplot (4.2.6 & 4.4.0) these plots take at least twice as
long to generate (>200ms).

For me, 100ms is borderline acceptable.  200ms is not.  However, my app also
has an interactive mode, so I would much prefer using a WXT terminal for
zooming because of its better UI...

Is there any known reason why a wX-widgets compiled gnuplot is 2x slower
when displaying PNG files?  Is there any way to fix this?

Thanks,
RM
