Performance


●
    Long term goals
    (< 1 sec for 99% of requests, < 5 for all w/enforcement)
●
    Problems solved
    object model assuming objects are free: eager load
    poor sql: tuning, schema changes
    python threads: don't use em - nearly linear degradation
●
    Problems that still need solving
    cold hits on large data sets: 10K objects @2ms each is still 20 seconds [e.g.
    assessing the size of a PPA]
    more denormalising, dedicated services
    search: lucene/lucandra
    ssl: front ends around the place with plain tcp in a vpn back to the datacentre
●
    Faster bzr-serve startup

Scared




         “Some people suggest
         putting my Tables on
         GitHub. But a) I'm scared of
         GitHub, and b) I need to
         retain editorial control.”
                                        “No, saying that GitHub is
           Peter-Paul Koch              "not much more difficult
           @ppk
                                        than CVS or Subversion" is
                                        not going to convince me.”

Don't be afraid to ask




                                     “I'm going to have to be a
                                     git grandmaster just so I'll
                                     have a proper retort when
                                     people insist I'll like it when
                                     I "truly understand it.”
