NAME

     mdls -- lists the metadata attributes for the specified file

SYNOPSIS

     mdls [-name attributeName] [-raw [-nullMarker markerString]] file ...

DESCRIPTION

     The mdls command prints the values of all the metadata attributes associated with the files provided as an argument.

     The following options are available:

     -name	  Print only the matching metadata attribute value.  Can be used multiple times.

     -raw	  Print raw attribute data in the order that was requested.  Fields will be separated with a ASCII NUL character, suitable for

NAME

       sys_attrs_presto - presto subsystem attributes

DESCRIPTION

       This  reference page lists and describes attributes for the Prestoserve (presto) kernel subsystem. Refer to the sys_attrs(5) reference page
       for an introduction to the topic of kernel subsystem attributes.

       The Prestoserve product consists of optional hardware (NVRAM) and software that must be	installed  on  your  system.   See  the  Guide	to
       Prestoserve for details on Prestoserve. See the System Configuration and Tuning manual for information about Prestoserve within the context
       of managing file system performance.

	      Size, in bytes, of the Prestoserve buffer hash table.

	      Default value: 256 (bytes)

	      Minimum value: 0

	      Maximum value: 65,536 (64 KB)

	      Increasing the value of the presto_buffer_hash_size attribute may improve throughput by decreasing Prestoserve lock contention.

	      A value that controls whether Prestoserve will cache only UFS and AdvFS  file-system metadata or both file-system metadata and  syn-
	      chronous-write  data.  If  the  attribute  is  set  to 1, Prestoserve caches only file-system metadata. If the attribute is set to 0
	      (zero), both file-system metadata and synchronous-write data are cached.

	      Default value: 0

	      Setting prmetaonly to 1 may improve the performance of applications that access many small files,  or  applications  that  access  a
	      large amount of file-system metadata but do not reread recently written data.
