Hi Chris,
- Jdk 1.5
- 32 bit server
-MySQL is setup pretty much out of the box. I tend not to consider
that as if I go directly to the DB via MySQL driver, it's fast. Are there
special considerations for the DB when using Sequoia? I.e. "make sure you
turn on the 'using sequoia flag'.
- No special JVM options on client or sequoia controller.Thanks, Randall -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christopher Hartung Sent: Wednesday, May 02, 2007 8:03 AM To: [email protected] Subject: Re: [Sequoia] Performance Yes, we use Sequoia to scale our reads and to create an active-active cluster environment. I think that the balancing is the point of this fast results. Some questions: - Which jdk do u use? - 32 Bit or 64 Bit 2003 Server? - Did you configure your mysql correctly? Maybe you can tune the backends (we tuned postgres a lot) - Are u using special options for the jvm? ... sounded very very slow :( so far, chris Randall Fidler schrieb: > Interesting... > > Are you using Sequoia to scale your DB reads?
