Request: kronecker to get a sep= argument
kronecker, with make.dimnames=TRUE uses a hardwired sep=":" in the line
tmp <- outer(dnx[[i]], dny[[i]], FUN = "paste", sep = ":")
For an application in which dimnames arise from an n-way array, where
different dimensions have
different roles, and I would like to be able to use kronecker in the form
kronecker(A, B, make.dimnames=TRUE, sep='/')

Oracle 9.2.0.6 on Solaris 10
How can I tell if this is normal behaviour? Oracle imports are horribly slow, an order of magnitude slower than on the same hardware with a slower disk array and Solaris 9. What I can look for to see where the problem lies?
The server is 99% idle right now, with one database running. Each sample is about 5 seconds. I''ve tried setting kernel parameters despite the docs saying that
