LBCache can halve your server load with vBulletin?
 

I found this while searching on how to fix server issues I am having:

LBCache, the vBulletin cache

Quote:
If you admin a server running vBulletin, it's almost certain that you'll have had problems with performance. There's plenty of scope for server tuning, and there are even a few modules for template caching; but what happens when you've implemented all of these, and performance is still poor?

LBCache is a PHP script which implements caching of forums and threads. Installation is fairly simple, the cache is highly configurable, and - best of all - the performance boost can be huge. Real-world tests on a busy server gave a halving of CPU load (and a similar reduction in the number of MySQL queries) when the cache was running. In situations where a handful of threads are being hit hard by visitors (eg if a thread has been Slashdotted), the reduction in load will be much greater. Benchmark figures below suggest that serving pages from the cache uses around one tenth of the CPU as non-cached pages.
The product claims to halve your server load and is written specifically with vBulletin in mind. Has anyone used this product and maybe have some feedback on it?
