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
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
