This is an attempt to summarize the issues around the performance problems
related to the installation failures reported in bug 13066 and other bugs
(for example 13321 and 13267).
13066:
It appears that there is indeed an issue with the network in the submitters
lab. While this is probably not the entire problem with not only AI but
pkg(5), the network issues need to be resolved before much progress can
be made determining what other issues there may be with respect to 13066.
Other groups are doing many more simultaneous installs without hitting
this issue or seeing the network failures.
Other possible performance issues with AI:
A couple of things have been identified here and there are various bugs
filed for these issues.
- AI should be using the pkg api. (bug 13851)
- AI needs to group calls to pkg install so that fewer repeated calls
are made. This is being addressed by transfer module changes.
All this being said there still appears to be possible additional
performance issues in pkg that will need to be looked into.
Jan detailed these:
[1] scalability problem on pkg consumer side (reported in comment #25 in
bug 13321)
[2] scalability problem on pkg server side (original report in bug 13321,
bug 13267)
[3] networking issue (bug 13066)
As Jan mentioned for #2 and #3 these have been seen with AI but should
also be looked at from DC in the same environment. This would help to
determine how AI contributes to the problem and aid in further debugging.
Are there additional issues around this that need to be looked at or other
things to think about?
Thanks!
