jdt's BatchImageBuilder.copyExtraResourcesBack() takes relevant time during clean build (example from platform workspace on windows):

Where the time is spend in LocalFile.copyFile()

While i have no idea how the LocalFile.copyFile() itself could be further improved (#1512) it might be possible to improve the whole thing with parallel processing as already done for delete/read/write (#1549) . Probably some parallel copy API has to be implemented in platform and used by jdt.

Contributions welcome.
