@vcunat:matrix.orgVladimír ČunátBecause I can see the huge difference between e.g. trunk and trunk-combined.17:06:42
@vcunat:matrix.orgVladimír ČunátWe're spending a surprising amount of Hydra's "real time" on the added tests.17:07:04
@vcunat:matrix.orgVladimír ČunátHydra's eval itself tends not to be a real bottleneck. (though in CI it would be bad)17:08:03
@vcunat:matrix.orgVladimír Čunát* Hydra's eval itself tends not to be a real bottleneck. (though in CI it would be very bad)17:08:14
@pyrox:pyrox.devdish [Fox/It/She] is there no way to parallelize the transaction by splitting it? 17:35:27
@vcunat:matrix.orgVladimír ČunátIt would certainly help with the deadlocks and blocking other updates to the DB.17:36:33
@vcunat:matrix.orgVladimír ČunátIt often happens that Hydra stalls for several minutes because of such huge write transaction just happening.17:37:14

@hexa:lossy.networkhexaor wait until we have a nixpkgs core team that can make that call?17:41:25
@vcunat:matrix.orgVladimír Čunát runCommandNoCC will surely have some usage outside nixpkgs, too. 17:41:50
@hexa:lossy.networkhexait was about e.g. pkgconfig = pkg-config back then17:42:07
@emilazy:matrix.orgemilyit wasn't very quiet IMO… it's only ones that were already in 25.0517:45:19
