We are working on CS14. Starting last Friday we are suffering form a extreme performance loss on CS14. Loading and Saving Metadata via Tooling/Metadata-API is very slow.

Operations which usually take about 2 to 5 seconds now take 100 to 400 seconds. We noticed such degradations earlier, but they usually did not last for longer than a day.

Now on CS 14, this situation is critical since Friday. Unfortunately we have no Premier-Plus to report this issue via support.

UPDATE: performance is going up and down. Today we got several hours of extreme unresponsiveness - now it's fast again.

Is anyone of you on CS14, too and can confirm that issue? Any ideas on how to contact Salesforce to make CS14 usable again?

I asked a more general question already: Are sandboxes slower than production Orgs? - This question should be very specific: focus only CS14 and only Metadata/Tooling-API

We get: enter image description here

  • Have you reported it to Salesforce? Mar 23, 2015 at 11:09
  • Yes, Case 11765428, but my experience with issues even slightly related to development were very disappointing without Premier Plus support... :-(

    There was an alert on CS14 this morning but it has been resolved (time of impact 0905 - 0929 UTC), hopefully it's better now for you!

    Having the exact same issue on CS17, since a month or so. Saving using the Tooling API is taking forever (metadata seems a little bit faster). Going through the Salesforce UI is a bit faster, but not convenient at all. I do get some Time Limit Exceeded errors when trying to edit some classes or pages thought. Same for unit test, running them all can take up to 4-5 hours.

    Today 2015-08-07 I'm on CS9 and the Metadata API is extremely slow for me. Looks like this is a systemic problem for sandboxes. Aug 6, 2015 at 23:57

There is now way to report such issues without Permier Support. Only thing you can do is wait, until performance comes back... Support responded like this:

Hi, I am Jasdeep from Salesforce Developer Support and I want to update you that the Developer support is currently available only to our premier customers and premier partners. We apologize for any impact this may be having on you.

Right now performance came back a few hours ago. But as bottom-line CS14 was unusable for development for several days. No chance of communication. No chance of support. That really sucks - even if the issue is fixed.

Worst thing is, we know it'll come back from time to time...

    Did you try the twitter channel? That might make a little more noise..

  • @theGreatDanton - Yeah, I know... keeping it up for the next time. Since a few hours, CS14 is on speed again. But the way they handle it just isn't all right.

  • reTweeted the issue.. I came across an issue with tooling API just today. When I query workflowAlerts with fullname field in the query I am not able to to retrieve more than 10 records, but if I remove it I get the complete results. Weird issues with Tooling API..

    @UweHeim - I feel your pain. I feel strongly that any individual that holds the advanced developer certification should be able to converse directly with a tier 2 or 3 support rep to triage dev support requests. Any request related to performance and not asking for "How do I do this" type of questions should be given the same priority as premier support. The certified professionals are the lifeblood of SF yet get treated like boil on the skin......BTW Been seeing the same issue on various sandboxes CS11 and CS 14 included

I'm having the same issue on CS14, and it's taking a good 20 minutes (1000 s) to get a Tooling API response on the Dev Console.

I found an article from about 4 days ago describing a similar issue, https://success.salesforce.com/issues_view?id=a1p300000008XvGAAU, and the article provides a workaround:


You need to edit the components on the UI by navigating to Setup | Develop | Apex Classes/Apex Triggers

The UI works for me though I wish I could be using the Dev Console instead.

    Thanks Amator, for confirming the issue. Somehow it helps a bit not being alone... It's incredible: yesterday afternoon, it was fast. Now is slow again. No way to work on that sandbox. Using the UI is no substitute for us. We have very complex code an need our own IDE (CodeFusion). This issue makes it impossible to use any IDE (no DeveloperConsole, no MavenMate, no Eclipse, no CodeFusion). That is simply not good enough and Salesforce should at least provide support for that.

  • this issue come and go. Today we got hours of total unusability - now it's fast again

this is due to the fact that there was a performance degradation at salesforce instance on which your sandbox is on, wherein Root Cause was that the problem was caused by inefficient requests which caused resource contention for a node in the database tier. To preserve core functionality for our customers on the instance, action was taken to isolate the inefficient requests, allowing resources to become available. As resources became available, normal performance was restored. So our R&D team has got the performance restored no on this instance.

The link you had mentioned on the case (this StackOverflow ticket), I have gone through that and whenever any one has encountered this slow performance issue, there had been a performance issue at salesforce end.

You can check on our site "http://trust.salesforce.com/trust/status/" to check on performance degradations at salesforce end.

Having the exact same issue in CS17 since the beginning of March. I reached out to the Salesforce support about it, and this is what they responded:

Thanks for your update. I understand you are following the best practice. I am afraid but there is no such process to assign more resources on a single Org. Since it is based on Multitenant architecture and resources are shared among multiple Orgs. We have implemented some methodology to prevent Orgs from monopolizing the shared resources.

Once we execute the test class it will go in queued statue and will start execution once resources are available. You may try deleting old test execution histories and compile all classes to see if it makes any difference.

Please let me know if you have any further query or concern.

I do understand the concept of the multi-tenant infrastructure, but we noticed a drastic unexplainable change in performance in the past month. Tooling API takes forever to process request, while Metadata API is a bit faster.

Going through the UI is also a bit faster to process requests (they must be prioritized over API), but it can take a long time to open the Edit page of an Apex class or Visualforce (sometime ending with the following error).

Time limit exceeded

Your request exceeded the time limit for processing.

Click here to return to the previous page.

Same for unit testing - they are being queued for 4hours, but executed in less than 10-20 seconds.

UPDATE: Here's a screenshot of Status - it seems to be only showing performance degradation for the past 4 days, but it lasted for the past month.

Performance degradation on CS17

    yeah, I can only confirm this. The situation is bad, especially if the customer has bought a Sandbox for 5-30% extra cost and then the developers can't work due to infrastructure reasons.

  • you are not alone: several others has issues in CS17 today, too... not sure how to proceed. I also heard that Premier Support does not help for this issue. You only get a "sorry-email"

  • @UweHeim I've updated my ticket with Salesforce official response related to the performance degradation. It seems like there was small improvement in CS17.
