Hi All,
could any one point out any open source test-suites for "File cache" testing and as well as performance test suites for the same. Currently my system is up with Linux/ext4.

Hi all
I saw in Microsoft web site www.SysInternals.com a tool called CoreInfo from able to print out on screen the size of the Data and Instruction caches of your processor, the Locigal to Physical Processor mapping, the number of the CPU sockets. etc..
Do you know if in Linux is available a... (2 Replies)
Hi again guys,
It seems this is a global thing affecting all the DNS bind versions prior to July 28 2008. I have my work cut out for me very soon, I see at least a handful of servers in my list that either need to patching or upgrading.
How many of you guys are affected? Anybody successfully... (4 Replies)

Cache::SizeAwareCache(3pm) User Contributed Perl Documentation Cache::SizeAwareCache(3pm)NAME
Cache::SizeAwareCache -- extends the Cache interface.
DESCRIPTION
The SizeAwareCache interface is implemented by classes that support all of the Cache::Cache interface in addition to the limit_size and
max_size features of a size aware cache.
The default cache size limiting algorithm works by removing cache objects in the following order until the desired limit is reached:
1) objects that have expired
2) objects that are least recently accessed
3) objects that that expire next
SYNOPSIS
use Cache::SizeAwareCache;
use vars qw( @ISA );
@ISA = qw( Cache::SizeAwareCache );
CONSTANTS
Please see Cache::Cache for standard constants
$NO_MAX_SIZE
The cache has no size restrictions
METHODS
Please see Cache::Cache for the standard methods
limit_size( $new_size )
Attempt to resize the cache such that the total disk usage is under the $new_size parameter. $new_size represents t size (in bytes)
that the cache should be limited to. Note that this is only a one time adjustment. To maintain the cache size, consider using the
max_size option, although it is considered very expensive, and can often be better achieved by peridocally calling limit_size.
OPTIONS
Please see Cache::Cache for the standard options
max_size
Sets the max_size property (size in bytes), which is described in detail below. Defaults to $NO_MAX_SIZE.
PROPERTIES
Please see Cache::Cache for standard properties
(get|set)_max_size
If this property is set, then the cache will try not to exceed the max size value (in bytes) specified. NOTE: This causes the size of
the cache to be checked on every set, and can be considered *very* expensive in some implementations. A good alternative approach is
leave max_size as $NO_MAX_SIZE and to periodically limit the size of the cache by calling the limit_size( $size ) method.
