    Want to compare insecure_nbd but doesn't seem to work (secure does)

        In XO, are you in http in Settings/server URL when connected, or default? (nothing, meaning https)

            Okay so compare secure NBD vs HTTPS perf then 🙂 I'm pretty sure NBD wins.

            Alternatively, you might try to raise the number of parallel NBD chunks to be download at the same time (@florent knows the setting I suppose?)

              @olivierlambert okay yeah I can compare to HTTPS. totally game to try whatever setting he's got to increase the parallel work.

              Insecure NBD would good comparison to http but I don't know how to turn that on, I know the purpose to set in host but there must be a config line to make it work in xo.

                It's only relevant to compare secure vs secure or insecure vs insecure. @florent will guide you when he's around 🙂

                    hi,

                    in theory, the insecure nbd should work when adding the insecure_nbd flag to the purpose of the network . Have you got any error message in the xo logs ?

                    you can add in the xapiOptions part

                    preferNbd = true
                    nbdOptions.readAhead = 20 # default 10 
                    

                    also do you remote store disks as multiple blocks ?

                    regards

                      @florent Yes to multiple blocks. I did see this in host>networks page.9d9de7d0-26b2-46e2-8729-09720ee65eab-image.png

                      I do (and did) have the preferNbd set.

                        @sluflyer06 we did a rework on NBD, to be able to use it everywhere, paving the way for some nice features like retry on network error

                        but it may have an impact on block based backup. I will make a branch which should alleviate this today

                          @sluflyer06 can you test the speed with this branch based on master https://github.com/vatesfr/xen-orchestra/pull/6840

                          The backup job must have only one remote , which must be block based, and without a continuous replication

                          Warning : this is not production ready, this branch is only to find where the potential gains are.

                          fbeauchamp opened this pull request in vatesfr/xen-orchestra

                          draft feat(@xen-orchestra/backups): use parallel reading whith NBD + blocks to only one remote #6840

                            @florent How would I verify for testing if its insecure NBD or not? I switched to your branch and rebuilt, I see the same message about not allowed but dunno if that matters.

                              @sluflyer06 For now , I get back to the first problem : NBD should be faster than xapi export ( or at least as fast)

                              now I 'm working on enabling insecure

                              edit : the not allowed is only to inform the user that it can't be set through XO, but it should be used for backup if present

                                @florent like Oliver was telling me, to compare secure to secure, it is faster than https,.still curious if anyway to try insecure.

                                Also. Is there a way to update XO (from sources) without losing the config.yaml or just a minor inconvenience until NBD is fully rolled into XO? (I assume we'll get told when we don't have to run custom config for NBD whenever it's ready?)

                                  @sluflyer06 the warning on XO is to discourage the mass. But you can really try

                                  you can make a config.toml file in ~/.config/xo-server/config.*.toml , it should be loaded , and won't be changed by an XO update . https://github.com/JsCommunity/app-conf
