[Zope] Re: ZEO with Multiple Storages

...

One ZEO server can deal with multiple storages just fine. Transactions involving multiple storages commit just fine.

Caveat: You buy nothing by having a single ZEO process serve several ZODBs when you're trying to decrease commit times. You should run a ZEO process per ZODB you're serving out, that way the writes can be segregated and parallelized. That also makes it easier to move processes/databases around disks/hosts to spread I/O load.

Just to clarify, you are saying that a single ZEO server would not be able to deal with multiple storages simultaneously and that a transaction in one storage would block transactions in all other storages. However, if we were to run multiple ZEO processes this would not be the case? -Brian
