What tools / client are you using to test to get the 200ms number? stu On Thu, Apr 29, 2010 at 7:12 AM, Viktor Jevdokimov <viktor.jevdoki...@adform.com<mailto:viktor.jevdoki...@adform.com>> wrote: Hi all, We have installed Cassandra on Windows and found that with any number of Cassandra (single, or 3 node cluster) on Windows Vista or Windows Server 2008, 32 or 64 bit, with any load or number of requests we, have: When client and server are on the same machine, connect/read/write latencies ~0-1ms When client on another machine, same network, on the same switch, connection latency 0-1ms (as a ping), read/write latencies >=200ms. What causes 200ms latency accessing Cassandra on Windows through network? Does anybody experience such behavior? Cassandra 0.6.1 Java SE 6 u20 Best regards, Viktor
