Data-writing from buffer to disk during indexing is I/O-intensive. Any other applications using the same server compete for disk access time. Sybase Search includes two parameters — index sleep frequency and duration — disabling the sleep duration parameter improves performance.
Index sleep frequency determines how many terms of data are written to disk before an index writing pause. Sleep duration determines the length of this pause, in milliseconds. The default settings are:
<SystemProperty name="omniq.indexer.sleepDurationMillis" value="20"/>
<SystemProperty name="omniq.indexer.sleepFrequency" value="100"/>
To improve indexing performance, set these values to 0 (zero) to disable index sleeping.
