@jennylaw - I thought you indicated before that if this was needed, that you (or someone on your team) would do compile Wincache for 5.4. However, I cannot find the post in which you stated as much.
Can you give us a timeline or at least a confirmation that the compilation of Wincache for 5.4 is in queue? If not, I need to know so that I can plan on making the time to try to do this myself. It's not something that I am comfortable with, but we really need this to happen (and so do several others.)
