# TermInfoReadBlockSize

The block size (in bytes) that IDOL Server reads from disk each time it retrieves term information. When you enable encryption, `TermInfoReadBlockSize` also controls the size of encrypted block that IDOL Server uses when it reads and writes terms.

In most cases, Micro Focus recommends that you use the default value. However, different storage devices have different characteristics, so you might be able to improve performance by modifying this parameter, particularly if IDOL Server is reading many terms, for example when it processes a broad Wildcard query.
