<p class="MsoNormal"><span lang="EN-US">Hi all, <br>
<br>
We use a fairly complex pipeline with more than 300 filters. <br>
<br>
When divided across 20 .pvsm , everything is fast. We started to merge those .pvsm into a single one.<br>
<br>
For the first 17 .pvsm everything was still fast. No .pvsm load time and no lag. <br>
<br>
Once we started integrating the 18<sup>th</sup> .pvsm the performance started to degrade. We used VTune to diagnose paraview:<br>
Seems that the performance drop is purely related to vtkInformation::GetAsObjectBase and vtkDemandDrivenPipeline::ComputePipelineMTime which is call recursively 37 times in a single call stack sample !<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It makes no difference if we integrate the 20 small .pvsm into a single large .pvsm or if we integrate thoses .pvsm as custom filters (.cpd) in the main .pvsm.

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This is true when we are loading the .pvsm, but this is also true when we are modifying values in the statefile.

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Any idea on how to improve the performance ? We though about dividing the pipeline into a multitude of pvserver</span><span lang="EN-US" style="font-family:"Times New Roman",serif">…</span><span lang="EN-US"><o:p></o:p></span></p>
