performance comparision between Zend Lucene and Java Lucene

Zend Lucene and Java Lucene are built in PHP and java repectively, and PHP language has a higher level than java.

Just wondering How big the performance difference among these two, regarding to index building and data searching?

Is i开发者_StackOverflow中文版t much more effective to let java create and rebuild index, and let php use the index?

This is a quote from a Zend Certified Engineer.

Against my better judgment, the company I work for migrated our previous search solution to Zend_Search_Lucene. On pretty heavy-duty hardware, indexing a million documents took several hours, and searches were relatively slow. The indexing process consumed vast amounts of memory, and the indexes frequently became corrupted (using 1.5.2). A single wild card search literally brought the web server to its knees, so we disabled that feature. Memory usage was very high for searches, and as a result requests per second necessarily declined heavily as we had to reduce the number of Apache child processes.

We have since moved to Solr (a Lucene-based Java search server) and the difference is dramatic. Indexing now takes around 10 minutes and searches are lightning fast. What a difference a language makes.

In this case, Java.

When I asked this question of a Zend Evangelist and one of their hired guns, I was told the Java Lucene would provide substantially better performance. Their main points dealt with the handling of UTF8 characters and the speed of indexing (if I remember properly). Apparently Java Lucene is far better at this.

Does Zend Lucene need Java Lucene?
