Today I encounter a severe performance degradation on Metadata-API deployment speed on EU5. I'm waiting > 950 seconds, when it usually deploys in < 25 seconds... 

Any idea what's wrong on that Pod? On EU2 it works fine as expected. Only EU5 seems to be slow. On trust.salesforce.org there is no problem visible. My experience is, that Metadata-API issues are not all reflected there.

No premier support available - can't report that issue.

UPDATE:

Not really sure if it's related but I found an earlier issue "related to asynchronious requests" which is flagged as "solved":
