Hi All,
I just thought you might be interested to see some performance benchmarks that I've produced recently whilst doing some work porting the Authcache module to D7.
I think the results are "pretty encouraging". What do you think :) ?
summary: ~1000 fold increase in authenticated user performance, 5 fold increase for anonymous users
1200 requests per second @ 2.5ms per request on a very modest single server.

Looks very promising, thanks
Looks very promising, thanks for sharing the data.
A D7 port of authcache is something my employer would be very interested in. I could potentially spend up 3-4 days on this right now and would be glad to assist in any maintenance in the long run.
Let me know if there's anything I can do to help you out.

Thanks !
It's a cliche, but right now the best thing anyone can do to help is download and test it :)
I'm expecting to have a full 7-x-1.x.dev release available from the main project page sometime today (hopefully).
It's approaching the point where I feel it's production ready (edit: for the adventurous) and I'm going to be trying it on one of my sites this week.
edit: there is now a 7.x-1.x dev release
solid state SATA hard
Wouldn't that explain in part the excellent numbers?
Would those benchmarks change much in a more available platform, like a RAID 10 system?
Thank you!
yes, but the important thing
yes, but the important thing to note is the "percentage" performance improvement.
With AuthCache (and FileCache) authenticated Drupal is 1000 times faster ...
It probably won't be quite as fast overall with mechanical drives but the degree of improvement will be similar.
Also, given that with FileCache (or MemCache) you're actually serving content direct from RAM it wouldn't surprise me if similar results were actually obtainable with mechanical drives.
Database queries will be much slower with mechanical drives, but we're not hitting the database :)
