-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Arthur, We have a database that has a table growing ~1,5M rows each month. The overall growth for the db is ~1GB/month. PostgreSQL 8.2.9 on x86_64 - a very modest Dell R200 with 4GB of ram. Although poor planning was made in the beginning (i.e. no clustering, no partitioning...) - we weren't expecting the boom :] - that particular server runs like clockwork with hundreds of queries per minute and still doing so without any noticeable speed loss. We're, of course, planning for load balancing in the beginning of next year ... :) BR, Pedro Doria Meunier GSM: +351 96 17 20 188 Skype: pdoriam Michelle Konzack wrote: > Hi Artur, > > I am owner of a database about War, Worcrime and Terroism with more > then 1,6 TByte and I am already fscked... > > Am 2009-06-15 14:00:05, schrieb Artur: >> Hi! >> >> We are thinking to create some stocks related search engine.
