Translation from Python to Go is now 90% complete. Early results indicate a speedup of at least 3-4x on fast-import-stream reads; if I get a similar speedup on Subversion stream reads (which I think is very likely) that should pull my GCC test runs down below three hours each. And more speed gains than that seem quite likely as I've only spend a couple of hours on performance tuning so far.
I don't know yet because most of the remaining 10% is in fact the Subversion dump stream reader. At least the major blocker I described in my last update has been removed; it's just effort and testing from here. Realistically, another serious attack on the repository conversion is probably about two months out. But progress is being made. -- <a href="http://www.catb.org/~esr/">Eric S.
