Re: [Boost-users] Lite serialization lib optimized for performance

"I think boost::serialization will find it hard to beat with its current design. Except for a smaller header which currently only keeps track of null pointers archive size is pretty much equal to that of a hand crafted solution." Why would that be? as far as I know an archive contains absolutely no data which can be eliminated and still have the system work. Where is the redundacy in the current archives?

I agree, I however tried to first achieve the desired results by just extending boost::serialization, but without much luck. boost::serialization is a very large library in terms of source code and it's pretty hard to wrap your head around the entire library. One of the motives behind me writing my own also was to gain the learning experience. My library isn't as robust and well designed as boost::serialization, but for use cases where performance and archive size is of importance I think boost::serialization will find it hard to beat with its current design. Except for a smaller header which currently only keeps track of null pointers archive size is pretty much equal to that of a hand crafted solution.

I'm convinced that the serialization library could be made to perform significantly better. To this end I've created a performance profiling framework which uses boost.build and library_status programs. As far as I know, profiling is only implemented in boost build for gcc. Anyway, I made the framework but haven't found the time to actually make the profiling tests. These would highlight any performance bottlenecks in the library so that performance could be improved. I've used this approach in the past on other projects with good success.

If someone wanted to have a big impact on serialization library users, he could make these tests and experiment with them. Perhaps this would be a good Summer of Code Project. Big impact - in a reasonable size project.

I'm guessing that efforts invested in this activity would have a much larger impact on boost users than trying to implement a "lite" version of the library.

Hi,

I've created a small serialization library which takes a lot of inspiration from the great works of Robert Ramey. The main difference is that my implementation has favoured performance and file size while trying to maintain most of the goodies of boost::serialization. The largest thing missing, I believe, is pointer tracking. I'd like to make it available both for review and others in case there's any interest for such a library, but know of no good public place to make it available.
