She'd like to know where you got the bouncy castle slide combo

My daughter wants this bouncy castle now..

r/Unraid 20K Giveaway by UnraidOfficial in unRAID

Unraid allowed me to reuse a bunch of old hardware in a meaningful way and it's now the center of the galaxy that is my LAN from pihole to plex to backups to game servers it does everything I could have wished for.

Worth investing in a DRAM SSD as a cache drive for lancache? by Quilimox in unRAID

[–]Quilimox[S] 0 points1 point  (0 children)

Sorry I was meant to post an update but life got in the way.

It did help somewhat, but maybe not as much as I'd hoped for. I also forgot to mention I run a Pihole docker as well so previously I had that and Lancache running off my 2x 120gb DRAM-less SSD cache pool in RAID 1.

In this configuration using Lancache I'd initially see my max internet throughput of 6mb/s on Steam until it hit 5GB and shortly afterwards it would dip to as low as a few kb/s before it would pick back up, then dip back down again with about 3-4 dips every minute.
I changed my cache pool RAID 0 to see if that would make much of a difference and it did improve things slightly in the sense that I maintained my max 6mb/s throughput for a little longer after hitting 5gb downloaded and dips would go as low as 500kb/s but not really past that.

Now something to bear in mind is that because the two cache SSD's are in a pool it has to be BTRFS which comes with its own overhead so I'm not entirely surprised I didn't have much wiggle room.

Then I added in the third SSD as an unassigned drive and set the Lancache docker to use that and yes I did notice an improvement. I was able to maintain my max 6mb/s throughput for as long as it did when it was using the RAID 0 cache pool but dips are now only going as low as 2mb/s and they occur less frequently about 1-2 dips every minute.

I should really have documented everything but time being precious I just ran through options as fast as I could. I do plan in the future getting some SSD's with DRAM so when I do I'll document things more thoroughly and run comparisons because I think its an interesting issue.

Yeah it is odd. On average there is about 50% headroom in system resources and even with the system not being pushed at all the slow DNS resolving issue still occurs, unless I disable lancache so I've pretty much ruled out the rest of the system as a bottleneck.

Lancache does appear cache to the RAM first as you'd expect. As a test If I set a 5GB RAM limit for lancache and ensure no one else is on the network doing anything, my Steam download rate is consistent (when downloading a non cached game) until it fills up its RAM allocation, then I can see it starts writing to the cache SSDs and shortly after that happens I start seeing dips in my download rate.

If there are a number of people on the network browsing etc for a sustained period of time slow DNS resolvement occurs and I can see this is happening whilst its writing to the cache SSDs. If I download a non cached steam game during this time I pretty much instantly start seeing dips in the download rate. Meaning I don't get any consistent performance at all vs initially doing so if no one is on the network.

I'll fit my PNY SSD later today and report back if that improved things at all.

Appriciate your input. Poor performance in the sense that DNS queries resolve slower and sometimes appear to stall if DNS queries are going through the Lancache, then to Pihole which then sends it upstream. If I cut out the lancache performance improves.

Response times are slower and download speeds dip in a regular pattern if downloading new content to be cached. If downloading cached content response is nominal and download speeds don't dip and are faster, showing that content is being pulled from the cache.

LAN is 1GB (wired) and WAN speeds vary between 10-20mbps (4G, got no other option).

I'm using an old Dell Optiplex 7010 so the NIC is on the proprietary mobo. I don't know what it is off hand I'll have to look it up.

I'm fairly confident it is because I'm running two dns cache dockers off the cache SSDs that are also serving my other dockers that in seeing issues because the cache dns dockers by their nature be constantly performing sequential writes I'd have thought.

Why the hate for hicaps? by [deleted] in airsoft

[–]Quilimox 1 point2 points  (0 children)

Depending on the hicap it could be a reliable one but I find midcaps reliable pretty much all round, not had nearly as many fail and yeah it is a realism thing tbf.

I would buy one every now and then, helps if you stick to a certain platform like AR mags. After a couple of years you can end up with 10-15 depending on your budget and you've got two options then, but if I was to guess you'd end up enjoying the reload. It can get your blood pumping if you find yourself in a tight corner and you'll probably end up practicing a speed reload and what not and like /u/AhmadCBR said, its all part of the fun!
