Heh, interesting. Something is leaking and causing a slowdown. The
good news is that we can extrapolate that the actual performance
will be >1.4k/s once we find that leak. You can probably get a hint
of that value by running a 2s blast.
I'll try to repro and find the problem (but most likely not until
next week).
I've known about this (nginx getting slower over time) but not had time to
investigate thoroughly. I think its an nginx-specific issue; it may be to
do with the fact that we're running in the special "non-forking" mode
(master_process off), or not.
If the problem is within nginx, then running nginx the same way in on a
regular system should exhibit the same behavior, right?
For comparison, I've just tried mathopd, and it does not suffer from the
same problem:

Transaction rate: 6676.46 trans/sec
Transaction rate: 6589.34 trans/sec
Transaction rate: 6657.97 trans/sec
Transaction rate: 6784.82 trans/sec
Any chance you could produce reference numbers for that with mathopd
running as a regular process on full-vm guest?
Thanks for the data, very useful.
Thank you from me also!
Thank yous flying all around.
