235	scale up to many nodes	zooko		"I updated [wiki:UseCases The UseCases Page] to reflect that someone might want to run a managed Tahoe grid comprising one thousand nodes.  (If each node has a single 1 TB hard drive, that's a 1 PB grid.  Obviously there are lots of other options, such as each node having six 1 TB hard drives in a RAID-6 configuration, resulting in 4 usable TB per node or a 4 PB grid.)

Anyway, we expect that the current Tahoe grid would have problems handling more simultaneously connected nodes.  One known problem is that pyOpenSSL uses almost 1 MB of RAM per SSL connection.  (See also #11.)

This ticket can be closed when Tahoe is demonstrated to handle one thousand simultaneously connected nodes smoothly."	enhancement	new	major	undecided	code-network	0.7.0		scalability memory performance openssl leastauthority
