Given your current hardware, software, product list, etc... how long does it take to run your queries in series? If you were able to run them in parallel and deliver faster response time to the users, would you implement PHP thread, if it's available?

Threading, Shared memory and PHP Do PHP really need support for threads? When and why is it necessary? Why should/shouldn't it be implemented in the core? How can one implement/create similar features right now? One reason I can imagine it to be useful, is if one has lots of SQL servers, and would want the script to manage the workload, or that if the servers might have different data stored that one needs access to. For example; one SQL server has account information, and another handles the messaging system, and the third handles generic information, and the last handles a product catalog with categories. And with threading, it would be a performance gain to be able to send the queries simultaneously to different servers. As for shared memory I think it is safer to use workarounds, but it would make it easier to create some classes, and would open up a whole new (high performance) way for classes to access shared data, that belongs to all objects and sessions. I also see a problem with shared web hosting, concerning both security and memory issues. For example, lets say the host has 10 clients running advanced systems, that place consistent data in memory, but only 2 clients has the need for the resources that the host supplies and 1000 connections at any given time, but the rest of the 10 clients only has 100 connections per day, and uses the same amount of memory as the more demanding clients. And then we have the problem with sharing memory across servers. Then we have the security issue that, if improperly configured/coded, other user/system can access the data, which arises the need for sandboxes or access control schemes. I fund some workarounds to this kind of problem by putting my energy on the code deign and analysis. I have a feeling that the most of the ones that yells the most belongs to the power programming group that skipped the part with architect philosophy. So basically I don´t need the support of threading or shared memory, I created the solution that works for me and my partners (with php only). But I admit that if there were native support for threading I would use it. But I don´t want the support for threading if it slowdown the performance.
