数据流2代运行很慢

[yjh]

将相同的m代码分别使用数据流1代和2代，几乎1代都比2代快，甚至可以快一倍。

Hi @yjh ,
Thanks for using Fabric Community.
As I understand, the issue is that Dataflow Gen2 is running very slow. Apologies for the issue you have been facing.  Currently there is no active bug regarding this issue.

This is not the expected experience, but it also depends on a number of factors such as your network, the data source, and our service. 

I'd recommend reaching out to our support team so they can do a more thorough investigation to see what could be happening and why it takes so long to query the data. I would request you to please go ahead with Microsoft support on this and raise a support ticket at this link : https://support.fabric.microsoft.com/en-US/support/.

Also once you have opened the support ticket , please do share the supportcase number here.
Please let us know if you have any further queries.

Thanks

对不起，我是试验性质的项目，所以并不急于解决问题，我只是提出一个dataflow 2gen 的性能普遍问题。
