Hi Brian, It helps, it's now at ~5s instead, but still at least 2x slower than on the 2.5 runtime.
So on December 1st, the 50% discount for front-instances is gone. The idea is to compensate by switching to Python 2.7 with multithreading, but it looks like at this point it's a lose-lose situation: it runs more requests at the same time, but they take longer. We're mid- November already, do you guys think you'll have all of this working perfectly within 2 weeks? The 1.6 SDK which actually allows to run 2.7 locally was just released, so we're only starting to test now. Seems to me deferring the payment change 1 more month to January 1st 2012 wouldn't hurt :) On Nov 12, 10:09 pm, Brian Quinlan <bquin...@google.com> wrote: > Hi Pol, > > Thanks for getting back to me. > > On Sun, Nov 13, 2011 at 4:50 PM, Pol <p...@everpix.net> wrote: > > Hi Brian, > > > threadsafe is "true" > > There is a known issue where concurrent requests (enabled with > threadsafe) can be much slower than non-concurrent requests, > especially if the request is CPU-bound. > > You might want to set threadsafe to "false" and see if that fixes the problem. > > Cheers, > Brian > > > > > > > > > Here's an example password_hash for an original 8 characters password: > > > $2a$04$cbM2uHwDphIG3jFFRpq1mui5aVjevnDUwhvQ77S/WG/qvJMpiXAL6 > > > On Nov 12, 6:58 pm, Brian Quinlan <bquin...@google.com> wrote: > >> Hi Pol, > > >> On Sun, Nov 13, 2011 at 1:48 PM, Pol <p...@everpix.net> wrote: > >> > Hi, > > >> > Since switching to 2.7 runtime, logging in tohttp://www.everpix.com > >> > went from about a second to anywhere from 15s to 60s.
