Package upload happens via xml-rpc, and to avoid holding the entire
contents of the file in memory, it's done in chunks. Unfortunately
python xml-rpc libs don't support keep-alive, so if you're using SSL
authentication you incur the non-trivial SSL connection setup/teardown
overhead for every chunk, in addition to the TCP connection
setup/teardown. The chunk size in your version is probably very small
(64k?). That has been increased in the Koji repo, but not released yet.
The next version will improve this situation somewhat.
Just wanted to write the same...
Naveen, you could increase your blocksiize as a workaround. Just search
for blocksize in /usr/bin/koji (function do_import)... I've done that
here and it helps. BUT do not set to too large, as for every chunk some
checksum (it seems) is being build (SSL does that I think) and the
larger your chunk the more CPU resources it will use!!!
