Can you elaborate more on the MySQL low performance on FreeBSD 7? From
my own tests the LAMP or rather FAMP infrastructure works very well on
FreeBSD. The performance issue is not only connected with OS per se,
but also overall planning of the whole infrastructure (hardware, HA,
load balancing, etc.), so it's a much more complex issue than simply
FreeBSD vs. RHEL.
We are trying to use Linux only on hosts that basically need it, e.g.
Oracle databases, OAS, multipathing to HP EVA/XP disk arrays, special
Linux oriented applications, etc. For the rest of the servers in DMZ,
FreeBSD is the only viable option. I am very happy with it for the
Internally we use also HP-UX and are extremely happy with its
performance and maintenance. IMHO it's much better for large scale
Oracle DBs or SAP than RHEL.
