01:43.34TorhalOr maybe just an owl which rides cows.

02:43.46znfhmm, even weirder is that I get decent-ish speeds outside of the VM
02:45.02znfBAH
02:45.22znffuck who configured this shit so badly 3 years ago :(
02:45.37quiescensyou!
02:45.45znfI wasn't working here 3 years ago :P
02:46.02znfI wouldn't have used qcow2 over nfs/zfs, I would have used raw files, for example
02:46.06znfor iscsi...
02:46.08znfor gluster...

02:48.26znfwhy I can't understand is why adding a log device and forcing sync writes degrades performance instead of actually increasing it
02:49.22znfby all accounts, forcing sync writes should write the data to the log device (which is a SSD), then every tgx_sync interval the data should be written to the actual physical disks that form the pool
02:49.57znfinstead, setting sync=disabled improves write performance by 2x-3x
02:51.27quiescensi don't really know of any setup where sync writes would increase performance over async
02:53.57znfbasically: https://www.ateamsystems.com/tech-blog/solved-performance-issues-with-freebsd-zfs-backed-esxi-storage-over-nfs/
02:54.33znfquiescens: sync writes *should* in theory complete faster on a flash device compared with the platter disks
02:55.42znfso technically the best solution would be to just "hack" the kernel
02:55.44znfwhich is stupid as fuck
02:55.55znfalso impossible to do in my case because it's in production
02:56.15quiescenswhere does that say anything about it being good to force sync writes?
02:56.32quiescensit seems to be talking about various ways to forcibly disable synced writes
02:57.12znfwell, if we'd take nfs out of the ecuation, forcing sync=always would improve the write speeds by shitloads
02:57.43znfI don't remember where I read it, I've read so many shits about this
02:58.28quiescensyou think writes are faster if you disable the ability to cache them, and force every single block to be fully written before returning control to the calling program?
02:59.46znfI'm honestly not sure anymore
03:03.18Torhalsync-writes quiescens.
03:03.27quiescensdies.
03:03.42znfI don't understand the initial design decision that was put in place for this system
03:03.53znfthey added 2x120GB SSDs for the ZIL/SLOG
03:04.01znfbut sync was set to disabled for the whole pool
03:04.09znfbasically they were never touched
03:21.47znfbut, regardless of these issues
03:22.27znfI still don't understand why I am able to maxx out the 1Gbps link when testing from the vm host, but when testing from the vm itself, all goes to shit :(
03:23.48quiescensiuno what issues you're talking about
03:24.13quiescenso.o
03:24.41znfuh, wait a second
03:25.00znfchanging the txg interval made my ioping produce decent results
03:25.07znfie: below 1ms replies
03:25.07znf:o
03:25.26znfavg. of 1.49ms
03:25.28znfthis is good
03:25.30znfthis is very good, quiescens
03:25.43quiescensi just don't get how you ended up with the idea that forcing syncs makes things faster ^^
03:26.46znfquiescens: forcing sync writes the data to the slot (ssd) first, before writing it to the physical disks
03:26.51znfs/slot/slog/
03:28.10quiescensit does, yes, but having sync left to application or disabled means it leaves data in ram until it is written
03:28.47quiescensthe purpose of having an SSD for write log, is so that when something does request a synced write, it can sync it to the write log and pretend that the data is synced
03:29.55znfyeah, I got it now

03:31.38znfI'm curious how this will work out once it fills up the whole l2arc
03:31.55znfnow that I've added an extra 180G to it
03:32.29znftechnically I should just remove the slog completely, no point in using it at all
03:34.16znfyes, I know I'm rambling
03:34.30znfI don't have a rubber duck here, so I'm using an irc-quiescens
03:49.26ls-znf: not a rubber duck, but still cute and produces kinda similar sounds https://instagram.com/p/Baer_3UA8mz/

18:06.40winkb) I use launchy, for Portableapps, files, etc.pp
18:06.50winkc) I have all the daily used apps pinned
18:07.04winkd) I start games via desktop icon
18:07.42winkbut to be fair. on this machine I hardly use any non-pinned applications, especially those from the start menu
18:08.12znfstart menu is my way of running things
18:08.24znfI never got the appeal of portable apps
18:08.35winkoneclick update once a month

23:32.31Gnarfozthat adapter is labeled "msata"
23:32.32nevcairielone is m2, the other is msata
23:32.59Gnarfozand even though there's a m.2 model, that's m.2 sata, but the ssd is m.2 pcie
23:33.39nevcairieleven if such an adapter could work (it really can't), it would be rather dumb to put two pcie nvme ssds on a single sata port =p
23:37.31znfI think I linked the wrong one

23:42.59znfor they do?
23:43.46nevcairielusually a bit, but if you value absolute performance consistency its usually best to keep a bit of spare room
23:44.01nevcairielwould need to check full reviews of those models
23:44.15znfI always assumed that 240GB SSDs are 256GB ones that have 16GB of over-provisioning
23:45.35znfoh, kingston says exactly that https://www.kingston.com/us/ssd/overprovisioning
