The number of threads was previously hard-coded, but is now configurable via the API and GUI with new properties called `{read,verify}-threads`, similarly to tape backups. The number of threads should also be configurable through tuning options or datastore config (as discussed by Chris & Thomas on list), which can be added in a follow up patch series. In my local tests I measured the following speed difference: verified a single snapshot with ~32 GiB (4x the RAM size) with 4 cores (just changing the read threads) 1 thread: ~440MiB/s 2 threads: ~780MiB/s 4 threads: ~1140MiB/s [0] https://lore.proxmox.com/pbs-devel/20250707132706.2854973-1-d.csapak@proxmox.com/#t Changes since v2: * split move to parallel handler into 2 seperate commits * add constructor to `IndexVerifyState` and clean up nits Changes since v1, thanks to Chris: * define dedicated schema for {worker,read,verify}-threads * rebase proxmox-backup * introduce new state struct `IndexVerifyState` to reduce the amount of Arc clones and overall better bundling * adjust update endpoint and UI to the new properties proxmox: Nicolas Frey (3): pbs-api-types: add schema for {worker,read,verify}-threads pbs-api-types: jobs: add {read,verify}-threads to VerificationJobConfig pbs-api-types: use worker-threads schema for TapeBackupJobSetup pbs-api-types/src/datastore.rs | 14 ++++++++++++++ pbs-api-types/src/jobs.rs | 20 +++++++++++++++----- 2 files changed, 29 insertions(+), 5 deletions(-) proxmox-backup: Nicolas Frey (6): api: verify: move chunk loading into parallel handler api: verify: bundle parameters into new struct api: verify: determine the number of threads to use with {read,verify}-threads api: verify: correct typo in comment api: verify: add {read,verify}-threads to update endpoint ui: verify: add option to set number of threads for job src/api2/admin/datastore.rs | 18 +++- src/api2/backup/environment.rs | 2 +- src/api2/config/verify.rs | 16 ++++ src/backup/verify.rs | 164 +++++++++++++++++++++------------ src/server/verify_job.rs | 7 +- www/window/VerifyAll.js | 18 ++++ www/window/VerifyJobEdit.js | 24 +++++ 7 files changed, 185 insertions(+), 64 deletions(-) Summary over all repositories: 9 files changed, 214 insertions(+), 69 deletions(-) -- Generated by git-murpp 0.8.1 _______________________________________________ pbs-devel mailing list pbs-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel
