We have a small database which size is 500 Mb. It is not possible to load these base in a computer with 2 Mb of RAM and loading the base in RAM is required. So, we shrink the database and it is ok with 350 Mb to fit in the 2 Gb RAM. First tests of performance on a basic request: 500x slower, yes 500x. This issue is reported to mysql team but no answer (and correction) Actually, the solution is running with a replication database: 1 node for write request and all the other nodes for read requests and the load balancer is made with round robin solution. -- Jean-Max Reymond CKR Solutions Nice France http://www.ckr-solutions.com ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
