Ofbiz in the wild

[Woyce Batkins]

Can anybody tell me by his own experience how scalable ofbiz is?  Are there
some numbers out there about some of the biggest ofbiz installations and
the type of traffic that ofbiz can handle?
Does anyone here have ofbiz running in a multitenant environment?
I tried to recommend ofbiz to somebody but he did some research and was not
sure about these things, also because there is a concurrent product from
the same people on the market.
Thanks.
