This message is cross-posted to both the zope and the PTK mailing lists. The restrictions I hope to hear about might be in both products. 1. The ZODB database we are using has passed 500 MB in Size (Yes, it is packed). It is about 50/50 populated with small news items and files of 1-4Mb in size. I expect it to pass 1 GB in 6-12 months. At present response is very good, both in retrieving items and in accessing the catalog. Does anyone has experience with much larger databases? Are there any build in limits that I should take into account. 2. The portal user administrion is based on a ACL-users folder. 70 users at present, expected to reach 500-1000 after we disallow anonymous viewing. Will that still work?
