( is it large <BR>> enough ? )<BR>> <BR>> In the past ( before SVN.3335 or something ) when running OpenSim, <BR>> just after the simulator goes Up, the OpenSim.exe process use around <BR>> 96 threads and everything works fine,<BR>> But, now, I saw that this number of threads reach 118 :(<BR>> As I posted in the past in Mantis that Mono under Linux is really bad <BR>> ( performances & coredump ) when you reach the limit of 170 threads ...<BR>> <BR>> When I connect 1 user to the sim : Thread count is now reaching : 157<BR>> When I connect a 2nd user to the sim : Thread count reach : 200<BR>> ( in that case : 200 threads used, the sim doesn't crash like in the <BR>> past but I find everything slow ... and my CPU is now 100% use / 7% <BR>> Ram used )<BR>> <BR>> Then, that mean, each time a user is connecting to the Sim, it use <BR>> about 40 threads ...<BR>> So, if I like to connect 20 users, I need around 40x20 threads = 800 <BR>> threads ...<BR>> And I'm not sure at all that Mono could manage that :(<BR>> <BR>> What's you're feeling on that point ?<BR>> <BR>> So, my question is : why not forking a new "OpenSim.exe" process for <BR>> each new connected user ?<BR>> Of course it's mostly for the standalone mode ( but the problem is a <BR>> bit the same in Grid Mode ) ...<BR>> <BR>> Maybe it's a simple/stupid idea from me, because I haven't enough <BR>> development skills to help all the people working hard to bring up <BR>> this marvelous simulator.<BR>> <BR>> Please, just let me know your position about it.<BR>> <BR>> Thanks a lot guys for all your dev,<BR>> <BR>> Regards,<BR>> <BR>> Ursula Matova<BR>> ( Of course this is my S/L Avatar Name :) )<BR>> <BR>> <BR>> _______________________________________________<BR>> Opensim-dev mailing list<BR>> Opensim-dev@lists.berlios.de<BR>> https://lists.berlios.de/mailman/listinfo/opensim-dev<BR><BR></body>
