Free Clear Purge System memory ( RAM ) in Linux.
Its best to leave the memory management to linus kernel but if you must clear up some memory then this is how you do it.
Execute this command as root:
sync; echo 3 > /proc/sys/vm/drop_caches
What does it do ?
sync; will write all the unwritten data to disk so that nothing is lost.
echo 3 > /proc/sys/vm/drop_caches; will drop all the cached data from memory.
WordPress vs vBulletin
It will be like comparing apples with oranges as one is a Blog Script and other is Forum. But both the scripts are based on similar technologies ( php/mysql) and there are some similar features.
WordPress’ look and feel is more in liaison with 2008/2009 technologies, vbulletin comparably looks outdated.
The installation, up-gradation, out of the box ‘SEO’, performance, adding plugins , changing skins and overall look and feel is much better in wordpress, pity wordpress doesn’t have a forum solution.
