Gremlins :-)

Me too.

This is coming up.  We are going to move all of our LDM related
data ingest/decoding (except the CONDUIT stuff) over to one of our
dual 450 Mhz Pentium II machines that is running Solaris x86 2.7.
It will be interesting to benchmark performance of that machine
versus our SPARC Ultra 2 and also to compare ldm-mcidas decoder
performance for executables compiled with Sun SC5.0 versus gcc/f2c
ones.  We have heard someone note that the gcc/f2c combination is
produces slower execution than the native compilers, but we don't
have any hard numbers.  Time to get some...
