Server Maintenance

[[NotD] localhost]

Alright guys,

I have finally recompiled the kernel for the main box with optimization in mind and was the reason why the server was down just a couple minutes ago. I've spent some time reading up on the options provided and am hoping that these new settings will finally provide a lag free environment since the last server reload.

I was almost ready to do a ram upgrade to 6GB, but it seems that SoftLayer will only do increments of 4GB which is $48 more a month. If we end up doing that, we will need to find some servers to add to our repertoire. I know we had a previous discussion about this, but I feel we did not reach any conclusion. The reason why I feel we do need the upgrade is because our free memory is usually near empty and is most likely the cause for deterioration in the quality of the server over the duration of a couple days.

So can you all do me a favor and post here and describe how the servers feel in relation to before. Also, what do you guys think about upgrading the server ram?

I say upgrade RAM we almost a year of server play in donations. They keep coming and if more tracers and other items are added people will keep wanting and donating.

I agree with Dr. Nick, I say do the upgrade too.

[[NotD] lespy]

upgrade for sure!

[FAMOUS]

upgrade for sure!

cho hows come you never call me to smoke some bowls or drink some handles???

If it makes life easier and games faster, go for it.  If it makes the zombies faster, then never mind...

Before I go about doing any upgrades, I will be recompiling the kernel and logging the differences in CPU usage.

Tomorrow morning I will test out the new kernel that come with loads of fixes.

My response $48 is nothing because the servers donate alot so why not give them the best servers.

Before I upgrade the server, I am trying to make sure that we solve the CPU problem. Some of the servers (ZH #1 and MG) use 100% of the cores that they are assigned to.

I am hoping that with the latest kernel I will be able to drop that CPU spike. I will do the RAM upgrade shortly after.

The last couple of days we have still been getting the occasional lag spike in the servers. Sometimes the tick will drop to between 10-15 for a minute or two in the ZH servers. Minigames I'm not sure if it happens, I haven't seen it while I was in there.

do y'all think on a zm mod there can be every kill of a zombie different amounts of points can be given to kill a zombie

You guys have already made your decision and I'm 100% for it, but I just want to say that we, as in Local, should avoid using too much of the donations just in case. I'm in no position to talk concerning the donations, but I thought it might be something good to point out. Being in a recession (I doubt we'll fall from the point we are at) the donations need to be conserved as much as possible due to expected inflation rates by the end of the year. I honestly don't think this really matters, but there has been a lot of discussion concerning this in the last few months. You guys really don't need to take much heed to this, but I thought it might be something good to point out. As long NotD is being donated to more than it spends we should be fine.

Alright, the upgrade has been completed and the servers have been started. Enjoy

@ShadowMomo I completely understand. NotD will always hopefully achieve the monthly goal.

Edit: I intend to recompile the kernel with a new CPU scheduler to see if it improves the overall quality.

Awesome Local, thank you.
