Hi all,

I've been experimenting with sharing resources between 2 rails apps with
AR and I just love it. The only downside is that when using AR, my app
slows down dramastically.

Is there a way to speed things up? Some special caching mechanisme that
needs to be enabled?

Thank you in advance for the information.

Are you running in development mode or production mode?

Just need to get this question out of the way first.

Hi Robert

I' running in production. I have noticed that development is slower then
production, but the production speed is still far from acceptable. The
diffrence between using ActiveRecord and ActiveResource is huge.

Yep, web services are generally much slower than SQL calls. There a lot
more work to do. Think about something like the Music store built into
iTunes that uses web services heavily. It's not exactly stellar
performance.

Who knows. Things like the work going into Rails 2.3 with RACK and METAL
may provide some opportunity to optimize ActiveResource, but I doubt
we'll ever see comparable performance between ActiveRecord (or other
ORMs) and ActiveResource. Improvements to ActiveResource will likely go
hand-in-hand with improvements to ActiveRecord so the gap will remain.

Can you define "huge?" Do you have any benchmarks. That might help
people here know whether it's really a problem or just basically
"normal."

Thank you Robert. I know that web services will always be slower then
connecting directly to the DB. But I have worked with external
webservices from third parties and my webservice is way to slow.

I have tested it again with a small benchmark by pulling a list of 50
items and displaying them. It took 28733ms to pull the data over and
display them on screen.

I know it's not a server or network problem.

Thank you in for your patience
