Now that you have the Accelerator running, how is performance?
There are two critical changes in the UBB6 design that can cause a performance problem when compared to 5.45.
First, all requests go through the scripts, including requests for threads. 5.45's threads are .html files, and did not require a call to the UBB script.
Second, the new file locking routines in 6.1 are designed to block all running instances of the UBB script when one instance needs to write a file. This is a very drastic measure, but it was required due to severe file corruption issues that have always plagued the UBB.
Using the Accelerator bypasses both of these issues - requests to cached pages (which include topics, the thread listing, the front page, and a few other misc. pages) are now processed without needing to start up an instance of the UBB, and therefore without the need to completely block when another UBB instance needs to write a file.
This, compounded by NT and slow IDE drives, resulted in your initial install running quite a bit slower than the 5.45.
Wait around for another day or so - you should find performance returning to "normal" once the cache builds up and the Accelerator can kick in properly.
Let's do a little informal calculation - enter your control panel. On the intro page there should be two hit counters - one for the total, the other from pages pulled from the Accelerator. What are the figures?
