    XML Sitemap extremely slow

    Hi, we're currently having an issue with the XML sitemap being extremely slow to regenerate after making content changes. We'll make a change in Umbraco, hit /sitemap.xml and it'll take around 10 minutes to load. Is there a way of improving the speed? Any kind of caching we could do? Any help would be greatly appreciated.

    Hi,

    It is generated dynamically. But cached after rendering, so next request should be fast. How big is the site, maybe exclude certain parts you don't want to add to the sitemap?

    Best,

    Richard

    Hey Richard, I'm seeing the same problem with a site (large number of nodes)... the url request just times out, and subsequent requests also time out. Where is the cached sitemap being held? Is it a physical file somewhere?

    This site is on Umbraco Cloud...

    Coincidentally, I also see the following error appear right about the time I hit the sitemap.xml link:

    Think the sitemap.xml file timesout. , performance is improved in 2.10 RC can be found here https://www.dropbox.com/s/7e5dp4zwdgnm02z/seo-checker210_0.zip?dl=0 But still it needs to loop over the whole site.

    Hope the RC fixes your issue.

    Best,

    Richard

    Hi Richard, thanks for your reply. The site isn't huge - around 70 pages. It happens on some of our other much smaller sites as well so I'm wondering if there could be something in the SEO checker settings that could be causing this?

    Hi,

    I found a really stupid bug. I's fixed now so few thousand nodes render in a few ms. Below the RC2 version of 2.10 where this bug is fixed

    That seemed to fix the issue so thanks for that. Do you have any idea when you're going to release version 2.10 to nuget?

    Hi again Richard,

    We seem to be getting the following error all of a sudden after copying the above DLL's:

    [BootFailedException: Boot failed: Umbraco cannot run. See Umbraco's log file for more details.

    -> Umbraco.Core.Exceptions.BootFailedException: Boot failed.

    -> System.InvalidOperationException: The migration plan does not support migrating from state "V2 Config Table". at Umbraco.Core.Migrations.MigrationPlan.ThrowOnUnknownInitialState(String state) in D:\a\1\s\src\Umbraco.Core\Migrations\MigrationPlan.cs:line 278 at Umbraco.Core.Migrations.MigrationPlan.Execute(IScope scope, String fromState, IMigrationBuilder migrationBuilder, ILogger logger) in D:\a\1\s\src\Umbraco.Core\Migrations\MigrationPlan.cs:line 304 at Umbraco.Core.Migrations.Upgrade.Upgrader.Execute(IScopeProvider scopeProvider, IMigrationBuilder migrationBuilder, IKeyValueService keyValueService, ILogger logger) in D:\a\1\s\src\Umbraco.Core\Migrations\Upgrade\Upgrader.cs:line 67 at SEOChecker.Core.Installer.SEOCheckerInstaller.Initialize() at Umbraco.Core.Composing.ComponentCollection.Initialize() in D:\a\1\s\src\Umbraco.Core\Composing\ComponentCollection.cs:line 32 at Umbraco.Core.Runtime.CoreRuntime.Boot(IRegister register, DisposableTimer timer) in D:\a\1\s\src\Umbraco.Core\Runtime\CoreRuntime.cs:line 188] Umbraco.Core.Exceptions.BootFailedException.Rethrow(BootFailedException bootFailedException) in D:\a\1\s\src\Umbraco.Core\Exceptions\BootFailedException.cs:80 Umbraco.Web.<>c.

    It seemed to work fine for a couple of days but broke this morning. Any ideas?

    I'm also experiencing unbelievable slow loading of the sitemap.xml It seems you were working on a version that fixes this but it doesn't seem to have been released yet. When is this update coming?

    Hi,

    This version is about to be released. I have fixed the slow sitemap already. You can use this hotfix version. I hope to release the final version within the next two weeks.

    Best,

    Richard

    Hi @Richard,

    Any chance you apply this hotfix to the 2.2.5 version for v7?

    I'm having this issue on a site that's using Umbraco 7.15.7, this site only has 25 nodes and it's painfully slow.

    Thanks, Ale

    Hi,

    We've recently upgraded to 2.10.0 from 2.9.0 and are now encountering the same error as @Myles mentioned above:

    -> Umbraco.Core.Exceptions.BootFailedException: Boot failed.
    
    -> System.InvalidOperationException: The migration plan does not support migrating from state "V2 Config Table".

    This error didn't appear in the logs till some 2-3 days post-release of upgrade. Do you have any ideas what is causing this?

    Just following up on this to say I found out this issue was actually occurring on our preproduction slot on Azure, not the production slot. The preproduction slots had the old DLLs as preprod and prod were swapped during the release process.

    Just in case anyone else encounters this issue, check your environments for older DLLs!
