Have previously struggled with the performance of site loading on my blog, always suspected that the problem was related to the database, but not really sure. But every time I have planned to find this out the problem has gone away, but lately the performance has been bad constantly. So off to Google, found the article about debugging B2Evolution http://manual.b2evolution.net/Debugging. First run, sloooooow, after that everything fast as lightning. Why did the problem go away? Beats me, suspect some MySQL-caching on the server, but must admit that I am guessing – honestly: I have no idea…but…debugging once helped somehow.
