Re: [Linux-cluster] MySQL on GFS benchmarks



Hi,

Ofcourse I understand that the performance will be less because of extra overhead. My goal is to be as close to standalone server performance as possible, with a certain budget in mind. One of the demands I have is that the cluster solution I'm building is transparent to clients, highly available, load balanced, and has to be scalable up to 2-8 servers. Both replication and mysql-cluster are not fully transparent, mysql on gfs can be I Think.
I'll keep the list updated when I get more benchmarks.

Best regards,
Sander

No matter what you do, a standalone server would be faster than a clustered architecture, if it is GFS over SAN, or even the MySQL cluster, due to obvious reasons of latency invloved. Anyway what exactly are you trying to build with MySQL, I mean what kind of performance you want from MySQL, may be you could try Replication or if you want good scalability, then you would be better off with the MySQL cluster.
