Could you share the dataset? Maybe I can reproduce the issue.<br>

Which version of PV are you using? You're not using the latest(4.1)
if --enable-bt isn't there. Upgrading to 4.1 may help...<div><div class="h5"><br>

So how much ram is on this system?<br>
How many arrays are you loading? If memory is an issue you
may get by by loading only one (or fewer) of them.<br>
What command line are you using to start the server?<br>
<br>
Can you start the client and server with --enable-bt on
the respective command lines? This should print a stack
trace during the crash. If it does send it to the list. If
PV is killed because its out of memory this may have been
logged (on linux: dmesg | egrep -i 'killed process').<br>
<br>
about your original question: When in client server(not
multicore) with the server running on a remote system and
the client on your desktop, the client only has to display
images rendered on the server. so very low load on the
client side. If you're seeing a high load in that case ,
remote rendering is probably disabled, perhaps this is a
bug.<br>
<br>
multicore would disable remote rendering , according to a
recent post on the mail list.<br>
<br>
mulitcore the client and servers run on the same system
and thus the X server load could in fact be coming from
the server rather than the client.

The connection I think is properly established
since it works fine for smaller datasets. What
should the load on the client be in that case?<br>

This includes data like vertices and colors as
well. X forwarding doesn't give good performance
and with large data it may not even be feasible.<br>
