The distance of the physical server has nothing to do with the latency being experienced. What needs to be verified before making a decision are
* Local bandwidth, how much is being used at certain times of the day * Are the packets going back and forth to the server taking priority over all other packets (is QoS implemented in your network) * What bandwidth is being provided by Equinox, can you get graphs for upload/download traffic * Is it the server that's causing the slowness o Memory o Configuration o Hard drive speed Hope this helps.

Our libraries are all in North Texas, but our server is in Georgia (hosted at Equinox). We often have problems with slow response time, and individual libraries have days when they get lots of network errors, which I assume are caused by timeouts. One library has days when they can't use Evergreen online at all, even though the other libraries are operating normally and the affected library can access other Internet resources normally. We also see quite a few cases where items get scanned for check-in but the system doesn't actually check them in, and I'm guessing that that's caused by network issues. Some of the problem might be caused by network infrastructure at the libraries or the ISPs serving the libraries, but we also suspect that the distance between us and our server might be aggravating the problem. What do the experts out there think? Would we see better performance if we shorten the network distance between us and our server?
