Sort of OT: My NebulaXLite product builds XML files that can get into tens of megabytes. Concatenation with either method described below can cause this process to take 1/2 hour or longer. I developed a technique that reduces build time of these large blocks down to seconds, and no, this isn't a method that has been discussed in public before. I know this would be valuable information to many companies that seek to reduce processing time of large blocks of data (CSV, EDI, HTML, XML, JSON, SQL, etc). I just can't think of a way to recover my research and development costs for this or anything else if the information is published in a forum for everyone to consume for free, or if the information is shared with a colleague who then provides a service to others to speed up applications without my assistance. Someone needs to pay for R&D like this or people simply can't continue to innovate - just ask your pharmaceutical company. So anyway, while I feel like a tease for saying so, if you find your X<-1> code still takes a Long time to process after you get to thousands of attributes or megabytes of data, just know that it Can be significantly improved, I just can't tell you how right now.
