Hi, I have added a new type of storage that is much faster than the one using SIXX. Of course the SIXX serialization could be optimized and it could be done in a background thread, but still it seems to be not very efficient. It is amazing: Saving the image costs less than a second on my machine, even with a wiki that has got thousands of pages and several folders with copies of my presentation. To enable the new storage execute the following code server storage: ImageStorage new. and a file called "smallwiki.im" in your image-directory will be generated every half an hour if something changed. Of course the storage-type might be swapped on the fly (hot-swap). Alexander told me that the XML-file of the running server is already over 1 MB. And I have my concerns that the VW XML-parser is able to handle very such large files to read it in. Therefore I think dumping the image scales far better and is more save, as it simpler and has been working for years now. Cheers Lukas -- Lukas Renggli http://renggli.freezope.org
