I spent a long time optimizing my site at http://bit.ly/eLl4uT Outside of factors that I can do nothing about (offsite chat), I think I did pretty good. However after…
Implementing New dedicated - 2x Dual Core Opteron, 16GB RAM, 2x 73GB SCSI 10k RPM, Hardware RAID1.
Implementing MaxCDN using custom URLs from a different domain (to maximize connections, when needed, without cookies).
My pages are much faster, the rub?
Time spent downloading a page (in milliseconds)
What is causing the increase? It corresponds exactly to all the above measures I took. Is it the new server? Is it MaxCDN implementation? How on earth do I tell?
