Hello Lin,

we worked indirectly on a case in the USA with 1/10 of the numbers you
mentioned. And we had terrible issues. Just to be clear we were called as
firemen and didn't had a chance to study things upfront on that project.
Well basically, 2 things became extremely slow: workflows because tables
were huge and stock moves (that was on 6.1) because millions of move to
crawl to compute any stock level.

On v8, there is good hope that the stock scalability issue is gone. As for
the workflows I'm afraid I'll probably still have issues: all workflows use
the same tables and open workflow instances of sale, stock, account
accumulate. My advice is: if it's on a version prior to v8, forget it
because of the way the stock moves work. If it's on v8, well in any case
plan some very serious optimizations and testing to see feasibility.

Number of concurrent users isn't too hard to tackle by adding more cores
now that we have process based parallelism, but as for very large tables,
well you'll have to clean them up often, you'll have tweak indexes,
probably to bypass some computations and use some custom SQL, add caching...
I never heard about sharding in OpenERP/Odoo so I guess nobody ever did
sharding, so don't assume it would be easy like in frameworks where it's
being done...

As for the company we worked for, well, after 18 months they ended up
dropping OpenERP for SAP. Probably putting way more money on it than trying
again on v8 and paying a lot of engineering to get the things optimized,
but still it's the decision they took and scalability was one of the main
reasons and that was 1/10th of the figures you mentioned. So don't take
that challenge lightly and good luck!

Regards.
