BC SAAS - Performance Issues

(0) ShareShare
ReportReport
Posted on by BC_Fan 5

We moved to BC SAAS around a month ago and the system is unbelievably slow compared to On-Premise via Azure.

Through our partner, MS have been investigating it but its taking forever and its having a real affect on our business.

Has anyone else experinced similar problems?

Does anyone know how to raise a complaint direct with MS?

    The first thing you should check is if you have any customized code that is causing this.

    According to statistics from Microsoft most performance problems for BC in cloud is caused by custom code.

    Support for BC online should go through your CSP partner so if you think the process is going slow you should push the issue with your partner.

    I agree with Inge M Bruvik's comment, the slowdown of SaaS is generally attributed to legacy code seeping into the modern SaaS environment. If you have a lot of customizations, I suggest get them reviewed & optimized by a Microsoft Partner
