Hi Mengu, Do you use the YAZ Proxy (https://www.indexdata.com/resources/software/yazproxy/) at all for load balancing Zebra? How do you distribute updates to your different Zebra servers? I have a vague memory that you index one of them and then copy the Zebra database over periodically?

Hi David, No, we didn't use never, unfortunately. We've tried some transfers between servers using with rsync, but it didn't reach a satisfactory solution. Instead we generally used to rebuild zebra at late nigths with huge memory servers. On 17.12.2020 02:43, dcook@prosentient.com.au wrote:

RAM is most helpful, but I looked into this (a little while ago) and the biggest hiccup seemed to be that Zebra won't multi-thread at CPU level -- it uses 100%+ of a single core, and bogs down. I remember writing to one of their developers in Holland (Adam D.), but never heard back. We have also found that RAID6 slows it down somewhat because of the write speed penalty. With best wishes all around for 2021, and please stay safe, Paul
