Hi So far we have put all data on a local drive (VM W2008R2). We would like to move data to a shared drive ( 30GB of data to be shared between three MapGuide servers for readonly access).
I did a test and created an alias using an UNC path pointing to a shared network folder. Same map, same SDF file, same layers, same scale and extent - the difference is enormous - consistently (tested on two different servers): Performance report : # sdf on local drive Total Generation Time: 664.23 ms Layers: 409.67 ms (61.7%) # sdf on network drive via unc/alias Total Generation Time: 8,683.02 ms 8,399.52 ms (96.7%) (Layers) I cannot rule out a slow network drive completely but it is unlikely (according to our IT): - UNC shared drive - we have this setup with MG 6.5. and it works very well - All data (VMwares, shared drives) use the same storage system Looking through the MGOS mailing list archive I see that perfomance and aliases were an issue in the early days of MapGuide (around 2007/2008) - but nothing recent. So, I'm curoius - has anyone else made negative experiences using an alias and shared drives? Is there something I can do with regards to configuration / testing? Any hints or suggestions? We are currently using MG 2.4, an update is not an option right now (due to dependencies). Many thanks, Rob
