Need PCIe SSD with Atomic Writes for MariaDB


I recently turned up a Hubzilla in addition to the Friendica Fediverse social media site here. Sunday it seemed to be okay but come Monday the server was seeing loads of around 150 or so at which point a number of web apps turned themselves off. Also it was exhausted on connections which made many peoples WordPress sites break.

After much fine tuning I’ve gotten MySQL to handle a touch over 400 transactions per second, but occasionally hubzilla spikes higher than that and the load will temporarily rise.

After doing some research on MariaDB and tuning it as best I could, now load only goes up to about 8 as opposed to 150, but virtually all waiting processes are waiting on DIsk I/O at that point so it appears that peaks are saturating the drives I/O capability. Already this is on a 4-disk RAID 10 array with everything pretty finely tuned.

Researching I am finding most people are not getting much better than 400 TPS on rotary drives and perhaps 500 TPS with M.2 SSD drives, but with a PCIE SSD drive that supports atomic writes, up to 1500 TPS has been obtained.

So I am searching for same but not having much luck. I can find lots of M.2s but can not find PCIE drives. When I search I only find PCIE SSD adapters, not what I need.

Does anybody know where I can source these and who makes them, perhaps some make and model numbers?

Maintenance


I am going to be taking our webserver down at midnight to backup and then to repartition the disk so that I can create a separate partition for mariadb tables so I can better optimize it for performance. This is pacific standard time. It may be down for several hours.

Hubzilla


New Federated Social Media Hubzilla

We’ve added a new federated social media platform called “Hubzilla“, hubzilla.eskimo.com/. It is similar to Friendica friendica.eskimo.com/ in that it is a federated social media platform but it has many more capabilities including channels that are similar to groups or blogs or user pages in Facebook but federated across the entire fediverse grid, although not all fediverse servers like friendica support all the features of hubzilla. It is considerably more complex however it is well documented online. Discovery of both users and resources such as channels is much easier and faster than it is with friendica and in my view the layout is somewhat nicer.

Hubzilla


I installed a Hubzilla instance tonight in addition to friendica, hubzilla.eskimo.com/ but I do not think I have it configured right. I can find other profiles on other hubs and other channels but no messages come across and when I try to view public stream it says, Public Stream App (Not Installed): The unmoderated public stream of this hub, but in the list of add-ons there is no Public Stream App and I do not know how to install it.

Kernel Upgrades affecting Friendica.eskimo.com


I will be doing kernel upgrades, both on the virtual host and physical hardware, upon which friendica.eskimo.com/ is hosted tomorrow evening (Friday February 19th) between 11pm and midnight Pacific Standard Time. Service will be interrupted while servers reboot.

Tickless Kernels


5.10.17 and 5.11 tickless kernels are now available:
eskimo.com/kernel/

There is both a "client" and "server" version of each. The client version is compiled to be fully preemptive and with a 1000HZ clock for minimum latency. The server version is non-preemptive and with a 100HZ clock for maximum thruput.

There are three deb files for each, download all three and install with:
dpkg -i *.deb

Nice video, by the way -- 'Red Pill'. haha!

No idea why it came back, but it did so not too long after this. By the way, when I log in starting from a blank screen, the default is 'Network'. I still don't understand the different choices -- apparently just sorting the database a different way.

One of the neatest features is the ability to look at a contact page, and see that person's comments, independent of which thread they were posted to. You can stumble onto some interesting conversations. Also, gives a good idea whether a person has anything to say, or if they are just a bot/news aggregator.

You make a valid point... but not really.

Now, had you opined that you were an imbecilic tool for the elite I would agree wholeheartedly.

But, you're a shill for the enemy which means you're not even human. Thus, beneath me.

How does my boot taste in your mouth, sub-human scum?

Global Warming 2021 - Shoreline, WA, USA about 13 Miles North of Seattle


Softare Defined Radios


A while ago I replaced my SDRv3 with a RSPdx and boy it was a big win. I'm in Shoreline WA about 13 miles north of Downtown Seattle, I'm presently receiving KAWS CSN International on 89.1 Mhz from Boise Idaho 494 miles. I've got longer DX's before but only with Sporadic E skip. There is some slow moderate fading but not bad. It's noisy but intelligable. Given there is a mountain range inbetween this is quite a catch. The mountains make troppo unlikely, the lack of serious fading makes sporadic E unlikely. So I have no idea what mode of propagation this is.
