 Posted: Fri Jan 20, 2006 4:08 am Post subject: *Solved* Server performance. |
 |
|
In concern of making use of best performance i checked the make.conf
I noticed some lines their which seem not apropiate with the server system.
Server is tyan bairbone with 2 x Amd opteron and 2gb dual ram.
Strange thing is that there are two processors in the system and that this line is included in /etc/make.conf
MAKEOPTS="-j4"
It should state -j3 ? i guess for 2+1 as stated in the /etc/make.conf.example file.
Should i change this value ?
Next this line.
CFLAGS="-O3 -march=k8 -fforce-addr -fomit-frame-pointer -ftracer -momit-leaf-frame-pointer -pipe"
This seems also strange because march=opteron would seem to be the best value ?
# amd64 CPU types supported in gcc-3.4: athlon64, opteron, k8
Should i change this value ?
# CPU types supported in gcc-3.2 and higher: athlon-xp, athlon-mp,
# athlon-tbird, athlon, k6, k6-2, k6-3, i386, i486, i586 (Pentium), i686
# (PentiumPro), pentium, pentium-mmx, pentiumpro, pentium2 (Celeron),
# pentium3, and pentium4.
#
# amd64 CPU types supported in gcc-3.4: athlon64, opteron, k8
# Please consult /etc/make.conf.example for a more detailed example
Make.conf starts here.

Could you please check the content of the make.conf to see if there should be anything added or removed ?
I ask this question also in relation to server performance https://forums.gentoo.org/viewtopic-p-3044630.html as gameserver since we have no clue yet how to improve the system performance.

I would suggest recompiling all the installed packages with safe CFLAGS.
I doubt that the MAKEOPTS being 3 or 4 makes a difference.
For a gaming server, see this thread. |

No
-march=athlon64 = -march=k8 = -march=opteron |

Does that system use SMP? If so, there should be FOUR virtual processors, in which case you might even want to use -j5. |

A new kernel was compiled. and that did the trick..
GameServer ingame ping times dropped from >30 to about 11 to 15 ms. Which is good enough for us 
thanks PaulBredbury and others for pointing in the good direction. |
