New submission from Goplat <mrnobo1...@yahoo.com>: Reading the list of files in a .zip takes a while because several seeks are done for each entry, which (on Windows at least) flushes stdio's buffer and forces a system call on the next read. For large .zips the effect on startup speed is noticeable, being perhaps 50ms per thousand files. Changing the read_directory function to read the central directory entirely sequentially would cut this time by more than half.
