I don't think multithreading is going to be implemented in lftp. I avoided it from the start as single-threading makes programming and debugging easier. But I think it is possible to squeeze more performance by optimization. First provide me with profiling information (compile with -pg gcc option, then run lftp, then run gprof, send me the output), then be ready to try optimized versions to see if they make a difference. -- Alexander. _______________________________________________ lftp mailing list lftp@uniyar.ac.ru http://univ.uniyar.ac.ru/mailman/listinfo/lftp
