Hi, Dave and Performers,

We found our CAVE applications extremely slow these days for
unknown reasons. The frame rate of a VRML model of 6 megabytes
dispalyed in Performer drops to 2 frames per second. The machine
is an SGI Onyx2 with 2 IRs, each having 4GE, 2RM with 128M texture
memory.

Are there any tools for graphics performance analysis and tuning?
The "top and gr_osview" doesn't help too much in this aspect.
Though Performer itself gives this kind of infomation, we suspect
something not fully configured in our machine.

One more thing, frequently we run Performer programs from a PC and
kill the process later. Are shared momery automatically freed in
this case? Maybe there are too much rubbish left in the memory because
of this ugly exit?

Thanks for any help and info.

Regards,

Liu
