Hi !

I found something interesting for those that use or are thinking about using Sumatra PDF-reader:


Sumatra PDF is a slim, free, open-source PDF reader for Windows. Portable out of the box. Sumatra has a minimalistic design. Simplicity has a higher priority than a lot of features.
It's small and starts up very fast. It's designed for portable use: only one file so you can run it from external USB drive. Doesn't write to registry.

I am compiling SumatraPDF from the original sources, to make freely available my optimized compiles. I am not modifying original code, but applying a different build chain to gather a better executable, in terms of native x64 support as well as regular x86; faster execution speed; smaller executable size; and lower memory footprint.

Of course, the rest of features, should be exactly the same as in official SumatraPDF. To prevent any possible confusion, my releases are groupped under the SumatraPDFOpt name, as an acronym of "SumatraPDF x86/x64 Optimized Builds".
