Subject Oddly slow replication
Date Mon, 07 Dec 2009 21:52:24 GMT
I have a Master server with two Slaves populated via Solr 1.4 native 
replication.

Slave1 syncs at a respectable speed i.e around 100MB/s but Slave2 runs 
much, much slower - the peak I've seen is 56KB/s.

Both are running off the same hardware with the same config - 
compression is set to 'internal' and http(Conn|Read)Timeout are defaults 
(5000/10000). 

I've checked too see if it was a disk problem using dd and if it was a 
network problem by doing a manual scp and an rsync from the slave to the 
master and the master to the slave. 

I've shut down the replication polling on Slave1 just to see if that was 
causing the problem but there's been no improvement.

Any ideas?
