Uwe Schindler commented on SOLR-4375: ------------------------------------- I was reviewing the mailing list. Actually only *one* user complained, but you did not ask him about backgrounds. Please note, he also complained about searches without term vectors are slower, which makes no sense, unless you look deeper into Solr and *how* he might use it: - There may be a slowdown if you have *every* field in your schema stored in Solr and you retrieve something like ten-thousands of results with all stored fields. - Term vectors and stord fields don't affect search times in Lucene, the problem is only post-result collection document fetching (see above) - If searches without term vectors are slower in Lucene that's easy to explain: I assume he highlights, too and this is faster with term vectors. This interesting detail about his index may also explain the stored fields slowdown: If he hoighlight also the tenthousands of documents he fetches, the current setup of Solr and the highlighter may cause stored fields to be read multiple times (because stored fields cache is too small). If you only read one small field for highlighting out hundreds of fields (all stored), the block-nature of the stored fields format may have an block-decompressing overhead (which is not related to the decompression, but more that blocks must be read). As mentioned before, everybody is free to change the default codec, no need for an extra setter. -1 to change anything without more details (schema, query URL thats slower,...). > Add config or schema option to turn off compressed stored fields in the > Lucene 4.1 index format > ----------------------------------------------------------------------------------------------- > > Key: SOLR-4375 > URL: https://issues.apache.org/jira/browse/SOLR-4375 > Project: Solr > Issue Type: Improvement > Affects Versions: 4.1 > Reporter: Shawn Heisey > Fix For: 4.2, 5.0 > > > There have been performance complaints on the mailing list about the default > compressed stored fields in the 4.1 index format.
