I found one possible solution.
Earlier in build script ant.signjar called sequentially for all jars (We use gradle for build, more than 20 MB dependecies). Now i use groovy library GPars methods: withPool(4) and eachParallel { ant.signjar }. It is cool for 2 cores in my pc and 4 cores in build server. (for 3 times faster)
Second trick is cache: we use cached signed jars for all RELEASE/NON-SNAPSHOT dependencies. When we run build without clean, it runs faster because uses cached signed libs from build directory.
