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.
