Hi Weihua,
This can't be right - x86 isn't MIPS. I assume you're running one of the
Altix systems. In that case, I'm afraid that as far as I know, there's
no native IDL for your architecture, and that's what affects your
performance. You may be running IDL in hardware emulation, which has a
severe penalty on performance.
Get the Intel IA-32 Execution Layer. I think SGI will be able to provide
you with a pre-packaged version of this, but you will always lose some
performance if you don't run natively. You have to make sure that IDL is
started using that emulation layer rather than the processor built-in
emulation, see the manual.
You may want to check out GDL, the open source IDL clone, if you don't
need widgets on that server.
Other things to check is how your graphics get to your screen - are you
running locally? Or are you running an X client over the network? This
can be really slow, especially if the network is in heavy use or has
configuration errors (half/full-duplex mismatch and the like). Try VNC
as an alternative to remote X.
Hope this helps

Jo
