I have 2 sites running on a multisite installation. Both are using W3 Total Cache, which has provided a significant performance boost to both sites. The "secondary" site is mapped using WordPress MU Domain Mapping.
The performance (page load speed) of the domain mapped site is significantly slower than the unmapped site, and I don't know if this is a normal trade-off with multisite or domain mapping? Any suggestions pointing me in the right direction will be appreciated.
The unmapped site is http://trianglehomesuccess.com/ I'm happy with the performance of this site on a shared host.
The mapped site is http://trianglenewhome.com/ This site is a tad sluggish, and I would like to find a way to improve the performance.
Any suggestions will be greatly appreciated!
