@vcunat:matrix.orgVladimír ČunátHydra the SW is coupled to the Nix version it's using. (though I don't know how much)17:28:06
@k900:0upti.meK900 Fairly heavily 17:29:05
@k900:0upti.meK900 But also RAM is not an issue 17:29:05
@k900:0upti.meK900 Generally 17:29:06
@k900:0upti.meK900 (and eval is generally not an issue most of the time) 17:29:30
@vcunat:matrix.orgVladimír ČunátWe don't seem to be really running into RAM shortage, though there's not a huge margin sometimes. (zram serves as a buffer)17:29:34
@vcunat:matrix.orgVladimír Čunát* We don't seem to be really running into RAM shortage on evaluations, though there's not a huge margin sometimes. (zram serves as a buffer)17:29:50

@wolfgangwalther:matrix.org@wolfgangwalther:matrix.orgCI's Eval also got faster with 2.30, although I don't know how much that was related to RAM usage and hitting swap otherwise.17:31:51
@philiptaron:matrix.orgPhilip Taron (UTC-8)What's the unit in these Hydra metrics for "allocations"? https://hydra.nixos.org/job/nixpkgs/trunk/metrics/metric/nix-env.qa.allocations18:03:45
@philiptaron:matrix.orgPhilip Taron (UTC-8)Number of mallocs?18:04:00
@k900:0upti.meK900 Yes, but also it's not really a relevant metric 18:04:57
@philiptaron:matrix.orgPhilip Taron (UTC-8)As in, when it goes up or goes down, not really an impact on stuff?18:05:28
@k900:0upti.meK900 Yes 18:06:09
