Oh my my~ It has been awhile since my last updates! I will kick start this blog again by providing my review to a Citrix technical book, with the title of  Citrix XenApp 7.x Performanc e Essentials by Packt Publishing.   To me, the title said it all. It explains the essential items for XenApp 7.x in term of performance. The instructions (followed by a few screenshots) given help readers to understand in the topic, and assist them if they want to dirt their hands with labs or training.  Note that there are huge differences between XA 6.5 and XA 7.x, and this book do the job well in explaining the 7.x technology, without making the readers to confuse with XA 6.5. A good read, moreover reference to Citrix Administrators, as well as the beginners.  You may check the book here . Well, this book does help me on my CCP : Virtualization preparation. But hey, that is not the focus here :)
