Slow WHMCS domain lookups are a source of frustration for some clients, as this, in turn, leads to loss of potential sales and reflects poorly overall on the business. Fortunately, this issue is generally a simple issue to resolve.
Slow Domain Lookup Causes
Typically, the speed at which WHMCS returns the requested domain name lookup results is directly related to the size of the domain lookup request, as in the quantity of top-level domains WHMCS is configured to provide per domain name lookup.
Resolving Issue of Slow Domain Checker
- From the WHMCS Admin area, navigate to Setup - > General Settings - > Domains
- Find the active domain name spinner, located near the top of the menu (Standard and Enom are the default options)
- Select "Configure"
- Review the "Additional TLDs to Search" and remove some options (ten or less TLDs will provide optimal domain suggestion speeds)
- Perform some test domain lookups to verify the performance has improved.
