Hi outthere,
We are using IDL on LINUX REDHAT9 and encounter the following problem
when we call a C- program using the SPAWN command in idl: The CPU load
of the C-program is only 30% while at the same time the system idle
process covers up with 65% (65% of the cpu is not used...)
If calling the same C-program directly in a bash shell and not from IDL,
the CPU load of the C-Program goes up to 99%...and the program is REALLY
faster....
Any ideas?
Cheers
