<div class=Section1>
<p class=MsoNormal>Good morning,<o:p></o:p></p>
<p class=MsoNormal>I am working with MGOS 1.2 RC1 and the latest GDAL FDO
providers on XP Pro.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a directory with twenty five 40MB MrSID files in
it. If I create a single data source against that directory, I have a limited
possibility that the images will actually process although there does not seem
to be any errors when I run MGServer from the command line. It appears that the
datasource is processed whether or not the layer is turned on.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>As an aside, I did notice that if I have the ECW dll
in the directory, the messages indicate that it is trying to read the .sid
format files as ECW which adds to the time.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In order to test things out, I created a data source for
each file. I noticed that for a couple of files, the processor usage
spikes to 100% but the images are displayed quickly. As I add more files,
the processor spikes become longer and the delays far more apparent. When
I get all 25 added my processor spikes to 100% usage for several minutes although
the images will eventually display. Watching the mgserver from the
command line shows that the images process and some go very quickly but others
seem to be very slow (which may just be the result of the processor being
pegged).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I tried using fwtools to mosaic these images together but
can only get about 4 together before I hit the 4GB tiff limit.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am trying to create a new single mosaiced .sid file to see
if that will make a difference but was wondering if there were any other ideas
of what I could do to improve the performance of the display of the images?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
<p class=MsoNormal>J<o:p></o:p></p>
