The Question is: I support a pair of MicroVax 3100-80's with about 10 users on each. Problem is that they complain about the screen refresh rate, which I have witnessed being very slow. We are using Decforms and you can at times see the windows being drawn. However, this problem only manifests itself on real VT's (a mix of 320, 420 and 520's) but not when using a Vaxstation, even over the WAN, where the screens draw instantaneously. The VT's are hanging off Decserver 700's with the latest images, but this problem is appar ent even with a VT directly on a TT port. Are there performance issues related to using Decforms on VT's, and is there anything that I can tune to speed things up (tried running the VT's at 9600, 19200 and 115200 baud, with no difference) Many thanks Kevin The Answer is : The Wizard is not aware of any particular DECforms issues. There is insufficient information here -- serial terminals are inherently slower than X Terminals, quite onviously. Start with the performance management manual, specifically the discussions around I/O performance. Check for sufficient process quotas, and make sure the system has sufficient resources -- AUTOGEN with FEEDBACK -- and check the value of system parameters such as MAXBUF. Please contact the Compaq Customer Support Center. The version of DECforms will be of interest, as will the ECO level.
