Barry and many others obviously find the performance of non-git VCSes acceptable. On the other hand, Brett has conceded that git's performance has enough fans that it has to be on the table (even though he admits to a strong bias against it, that's the major concession).

Oy! "Non-git VCSes" indeed! :-)

Barry and others find the performance of Bazaar acceptable. I (and equally many others, I believe) don't. Mercurial is significantly faster than Bazaar (I don't know how Mercurial speed compares to git but both are orders of magnitude faster than Bazaar in at least some cases).

I believe that the performance of Bazaar is still its major disadvantage, regardless of the Bazaar developers' ongoing work on the issue and the often-repeated "well, yes, but if you do things this way, that's much faster" workarounds.

Performance is always a consideration. IMO, now that it has been acknowledged that performance varies considerably among VCSes, it's more important at this point to figure out what Python development's other requirements are.

That is a fair point. My instinct is that python-dev's requirements on a DVCS are likely to be fairly basic (at least initially) and most DVCSes will be able to satisfy them. At that point, the arguments get more difficult ("nice to have" extra features which may not actuially get used in practice, we don't know without experience, versus immediate performance benefits which could easily change over time).
