I have a large file of size 1.2GB which zsyncmake2 performs much worse than original zsyncmake on. Is this expected?
$ time zsyncmake2 FILE.tar
zsync2 version 2.0.0-alpha-1 (commit ), build <local dev build> built on 2023-03-08 11:03:16 UTC
No URL given, so I am including a relative URL in the .zsync file - you must keep the file being served and the .zsync in the same public directory. Use -u eikefet.tar to get this same result without this warning.
Warning: the given URL is relative. Please make sure the files are placed correctly on the server, otherwise zsync2 won't be able to resolve the path to the target file, requiring the user to specify this URL on the command line (using the -u flag).

However, zsync2 is faster when redownloading the file.

zsyncmake2 wasn't really developed with performance in mind. It does consume an entire CPU despite being relatively slow. I'm sure it could be improved further.
Hello.
Thank you for this rewrite of zsync.
