I did not aim for that. And note that I currently have a lot of debug output, and also some unneeded conversions string -> stringstream -> string, so I believe that Bennets numbers are not bad. I would have expected worse numbers. > You are putting in the chain > lyx2lyx parsing + lyx format parsing which is known to take some time. lyx2lyx only if the format is not recent, so lyx2lyx will not be called if this is used as a workaround on the Mac.

First, the multiple view feature is still not finished, and AFAIK it is still not decided whether it will be made visible in 1.5.0 or not. Second, I usually start several instances of LyX for several documents. This has the advantage that if one instance crashes the other ones do still live, and I don't have to load the ither documents again. Sometimes one instance is even running on another machine, e.g. when I am prerparing large lecture notes that need to be compiled often and take some time. > If we are going that route then I would prefer that you use binary dump > of the internal structure instead.

To me it looks far better to use this patch: - It has the advantage of increased interoperability - Mac users with a working QCliboard::ownsClipboard() will automatically use the fast internal version. The workaround would probably not allow that, since testing for it would I agree with you that clipboard/selection is OK for 1.5.0 (almost; I'll write a summary later). My reasons for finishing this patch where simply: - It was lying around here unfinished for over a year, and I wanted to have that since ages - It solves the Mac problem without the need to invent another workaround.
