	Hello

	 

	We use top command for checking system performance and many found that lot of memory is cached like one below

	 

	Cpu(s): 28.2%us,  0.1%sy,  0.0%ni, 71.7%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

	Mem:  74175192k total, 73199960k used,   975232k free,   910828k buffers

	Swap: 104856244k total,  1565532k used, 103290712k free, 65612288k cached

	 

	Can some body help us understand what is really cached? Is this available for required process on demand? 

	Unable to get clear info about this.

	 

	Many thanks in advance.

	 

	Rgds

	Nitin

	
	

Yes, this is available for requiered process on demand. 
 You can find detail from http://www.faqs.org/docs/linux_admin/buffer-cache.html
