Is it a big challenge for Solaris to frequently reallocate contiguous memory? For example, if I choose 32K MTU, is it very difficult to Solaris frequently reallocate 32K memory? For IPoIB project, I think IOMMU is not a issue. Best Regards Kevin Ge _______________________________________________ networking-discuss mailing list [email protected]
