Mail NETvigieHi, I buy a new DELL PowerEdge 1850 with Bi-Xeon 2.8GHZ/2*2MB Dual Core 800FSB processor, 2Go DDR2 RAM, PERC4di RAID controller with 2 SCSI U320 15.000tpm 36Go hdd on RAID1. I install on it Freebsd 6.0, apache 2.2.0 and mysql 4.1.18 and compare performance with : OLD PowerEDge with only simple Bi-Xeon 3.0 GHZ and freebsd 4.11. Result is that web and local databases query are +- 4 times slower with freebsd 6.0 and dual-core. I try with and without smp and threaded kernel and results are same. I came back to Generic kernel to see if it come from my kernel configuration but result was same. I then think it come from hardware configuration, call DELL, then I change lots of settings but result was same. I then try to install a slackware distribution and have really good performances. Do you have any idea? Do you think 6.1 release will be ok? N.B : I run ubench tests but I don't think result is significative
