-----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of VeeJay Sent: Wednesday, June 04, 2008 4:04 PM To: FreeBSD-Questions; VeeJay Subject: New Kernel with Dell PE2950 Hi guys I am going to install a Web Server (apache+mysql+php) at my work place. To boost performance, I am just thinking that should I configure and rebuild FreeBSD KERNEL for this hardware? And if so, what paramters I should follow? Any help would be highly appreciated. Server's hardware configuration is as follow: 2 x Quad Core Xeon E5450 3.0GHz,2x6MB,1333FSB 16GB (8x2GB Dual Rank DIMMs) 667MHz FBD 6 x 450GB SAS 15k 3.5" HD Hot Plug PERC 6/i, Integrated Controller Card x6 backplane PE2950 III C5 MSS R10 Add-in PERC 5/i / 6/i 1 S TCP/IP Offload Engine 2P Broadcom TCP/IP Offload Engine functionality (TOE) Not Enabled Thank you guys. VJ BR / vj You should start by using some sort of benchmark or traffic generator and trying to overload the server by reproducing your environment. This way you will see exactly what parameters needs tuning. Bottleneck can come from many things....IO, NIC, database and so on. It is not like you will apply some universal tuning that it will solve all future issues. BTW....bce/bge drivers has known issues that leads to 'watchdog timeout' NIC reset. I have same some 6-8 servers with your hardware configuration and we have ordered them with Intel Gigabit cards especially to avoid above issue. Use bce/bge NICs for low traffic interfaces if possible. Is there any reason why GENERIC/SMP kernel does not suits you well? What is your traffic expectation for the server?
