User blog:The Lord of Minas Morgul/Fastcraft Alternatives?

I decided I was going to get Fastcraft, but when I went to the download site (on the link that Mevans has provided) and clicked the link. I proceeded to download it, but before it was completed, my anti virus software told me it had exhibited risky behaviors. So I cancelled the download and continued to deal with lag in ME. So, does anybody know if there is a fully compatible mod that decreases lag in Minecraft? Thanks in advance,
