There can be a number of reasons that survey plans are slow in Quickmap. Typically survey plans are slow because the antivirus software installed on you PC or server is interfering, but this can also be caused by network issues.

To fix this, you can fix any underlying network issues and exclude the survey plans from the antivirus scanner. Alternatively, if you upgrade Quickmap to the latest version, then you can disable the use of local survey plans and just use the free online survey plans.

This is a good option for troubleshooting the problem (to ensure that accessing the local is definitely what is causing the problem), but also worth doing to get access to all the additional survey plans that are made available online.
