In April I started to take care of the time response of the WordPress blog.
After adding wp-cache, CDN, and check the quality of the code, the results are:
1.- Yslow grade = A, overall performance score = 96
2.- Load Impact: it’s not perfect, but goes from 7.5s to 5s average, and only 2 high peaks.
3.- WebPagetest: this one comes from 72/100 to 93/100, First Byte Time is still bad, compress images has decreased and Cache static content has improved.
The job is not perfect but for me, now it’s time to go for Prestashop!
