I am working on SharePoint 2010 Cloud (Private Cloud hosted by a vendor). and developed some custom XSLT List Views. Now I am facing an error
"Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator"
There are many solutions on web and almost all are common to increase "XsltTransformTimeOut" value to 5 seconds using powershell command, as it is 1 second by default. But when I requested to vendor they are showing concern as It can impact performance of the SP Farm or other sites also.
I am not able to find any major performace impact related to this parameter as this is only related with XSLT Views, and XSLT is very usefull in case of cloud where we have customization option through designer only.
Please help me with other possible performance impact if we increase "XsltTransformTimeOut" value to 5.
