We recently moved from an x-serve to a windows server and even though we had slowdowns before. Now we get intermittent slowdowns. Indesign freezes for about 1.5 minutes. This happens sometimes several times a day, somtimes a whole day can go without the slowdowns.
The server is a HP DL380p gen8 with fast SAS-disk in Raid 5. Virtual Windows Sever 2012. No other users are affected by the slow downs. Only Indesign users and only some times. When we had the MAC-server, things were bad at times, but now it's clearly worse!!!
We are also using ExtremeZ-ip-server for AFP-shares to the server.
Edit: It seems that the connection to the server is broken when this happen as it disappears in finder.
