Juesthmmm, so?20:45
Juesthmmmmmm interesting stuff Agatha, thanks for chiming in!20:45
Juesttupone: raid 1 is unfortunately really slow especially if you use it for the os drive20:46
Juesti suggest checking the chip and stuff on that ssd brand, maybe there's someone who looked into it20:46
blast007Juest: might depend on the SATA controller.  If the controller can't sustain full speed writes to both drives, then it would be slower.  If it can, then write speed shouldn't be any slower, right?20:53
Juesthmmm fair enough, yeah, that might be it20:54
*** Sgeo <Sgeo!~Sgeo@user/sgeo> has joined #bzflag20:54
Juestsata3 is essentially a minimum for that i suppose?20:54
blast007And in *theory* the read speed of RAID1 can be faster than a single drive, but I don't know if mdadm reads from both drives at once.20:54
Juesti thought it reads from both drives for verification instead of one20:55
Juestbut definitely writes are slower because they're duplicated20:55
Juesti suspect the issue here is the latency and clogging from the mechanical drive performance and controller overhead?20:55
Juestits too slow and i probably could reproduce this if i were to have a disk intensive operation running while trying to play20:56
Juestreads hurt the most20:56
Juestbecause they happen more often20:56
blast007could also be a failing disk that it causing performance differences between the two disks20:57
Juestthat too20:57
Juesti'd check smart in that case20:57
Juesti have a working hdd but really fragmented and slow but no smart issues at all20:58

tuponeI suppose that mesa is doing sync() otherwise I don't explain it21:29
tuponeIt should buffer any write, and don't wait for disk to have it doing is work, unless you ask it with sync21:32
tuponeIIRC, Mesa developers has fixed some lost file handlers, used for disk write caching. Maybe they fixed using sync ?21:34
