If this is while you are indexing, then it simply means that you are not feeding documents to Solr fast enough (use multiple threads to send to Solr, and send multiple documents in each update request if possible). If CPU utilization is still low, then it means you are IO (disk) bound... if you want to go faster, get faster disks. -Yonik > Do I have to change a parameter ?? > > Thanks a lot , > Johanna > > > Walter Underwood wrote: >> >> Try running your submits while watching a CPU load meter. >> Do this on a multi-CPU machine. >> >> If all CPUs are busy, you are running as fast as possible. >> >> If one CPU is busy (around 50% usage on a dual-CPU system), >> parallel submits might help. >> >> If no CPU is 100% busy, the bottleneck is probably disk >> or network. >> >> wunder >> >> On 2/20/07 10:46 AM, "Jack L" <[EMAIL PROTECTED]> wrote: >> >>> Thanks to all who replied.
