我有一个ruby脚本,使用rsolr rubygem生成XML并将它们发布到Jetty Server浮出的Apache Solr(javadoc Update Command)。我的脚本使用以下代码记录特定时间
405 unless docs.empty?
406 begin
407 log.info("Adding to solr")
408 response = solr.add(docs)
409 log.info("#{(id_2*100.0)/last_id}% Done")
410 if response['responseHeader']['status'] != 0
411 log.fatal("Document ids not sent")
412 #log.fatal(Solr::Request::AddDocument.new(docs_single).to_s)
413 log.close
414 exit
415 end
416 log.info("#{Time.now.to_f - starttime}s to feed Solr. #{id_1} to #{id_2}")
417 rescue Exception => e
418 log.fatal("Document ids not sent => ")
419 #log.fatal(Solr::Request::AddDocument.new(docs_single).to_s)
420 #log.fatal(docs)
421 log.close
422 exit
423 end

根据这个日志,Solr采取(42.18 - 3.29 - 1.49 - 2)35.4s作出回应。 (见下面的评论)
同时,此特定更新的Solr日志与
类似INFO: {add=[5879999, 5880000, 5880001, 5880002, 5880003, 5880004, 5880005, 5880007, ... (1468 adds)]} 0 5780

Oct 9, 2011 3:04:42 PM org.apache.solr.update.processor.LogUpdateProcessor finish
这清楚地表明,Solr花了5.78秒来添加文档,启动响应发送并关闭日志更新程序。
这两项服务都在同一台机器上运行,在网络内运行,并且它们的ping摘要是
rtt min/avg/max/mdev = 0.008/0.010/0.022/0.006 ms
对于处理的每个批处理数据,此模式清晰可见。尽管我真诚地努力解开这个谜团,但我无法理解这种行为。
