Wow! That's super. Now about the only thing left is to get it included in the standard kernel. Do you think Linus Torvalds is more likely to accept these patches than Ingo's? I sure hope this one works out. > This is one to > three orders of magnitude better than BeOS, MacOS and the Windowses. ** salivates ** > - Low latency will probably only be achieved when using the ext2 and > NFS filesystems. Well it's extremely nice to see NFS included at least. I was really worried about that one. What about Samba? (Keeping in mind that serious "professional" musicians will likely have their Linux systems networked to a Windows box, at least until they have all the necessary tools on Linux. > - If you care about latency, be *very* cautious about upgrading to > XFree86 4.x.
