basis, the 22nm Ivy Bridge will double the number of executive units to up to 24, which will naturally lead to a further leap in performance. It has also been reported that Ivy Bridge will finally join the DX11 support. The current 32 NM bridge architecture processor was officially launched on January 5 in 2011, so for the next 22 nm Ivy Bridge Architecture processor, we can expect it to be launched in about a year's time. Another new desktop platform based on Ivy Bridge architecture will be

The apt-xapian-index package is very convenient to use, but I am always exhausted (the first line): There are two solutions online: 1. delete apt-xapian-index, but after deleting it, quicksearch cannot be used and it is inconvenient to find the software.

When migrating a database to a multi-database server, in order to save time, we may directly detach a database and then directly use the MDF file to attach the database to another server. In this case, all cache plans will be cleared out of the buffer zone. As a result, the CPU usage will remain high for a period of time. Apart from separation, the cache will be cleared. Other operations include: Setting the database online or offline, renaming the da
