Trick to Optimize Winbatch Execution over a Network

Question:

Many users have a dial-up networking link to a server. When trying to run WinBatch scripts over this rather slow dialup link, the download of the Winbatch EXE and DLLs takes forever. Are there any optimizations for this?

Answer:

There are several different techniques. Also read Article through W13170 for optimization issues.

• Having a large-model WinBatch EXE on the server is worst, as the entire EXE is transferred to the users memory, and most of it is not used, as it accesses the server for the DLLS. Making small-model exe's helps a lot.

• Once you make small model EXEs, it can be noted the EXE's are much smaller. The time consuming portion is the DLL transfer to the user's machine. If the users machine can be pre-loaded with the DLLs (and they do not exist in on the server), the small EXEs downloaded from the server will use the local copy of the DLLs, and vastly speed up the transfers.

  The problem here is that if you update your version of the compiler, often you have to figure out how to get the latest versions of the DLLs to the user.

• Another very fast technique is to use the compiler to make a WBCRUNNER.EXE
  1. Create a one line script called WBCRUNNER.WBT

     ;WBCRUNNER.WBT
     CALL(param1,"")
     

  2. Compile the WBCRUNNER.WBT script using the 'Small exe for Networked PCs".

  3. Install the resulting WBCRUNNER.EXE (and any required DLLs) on the user machines. (i.e. c:\runtimes\WBCRUNNER.EXE)

  4. Compile any scripts you want to execute using the 'ENCODE for Calls from Exes' compiler option to make a WBC file.

  5. Now to run it from a login script, add the following line to your login script:

      
     START /W c:\runtimes\WBCRUNNER.EXE \\server\someplace\yourscript.wbc
     

  The effect of this is that the WBCRUNNER.EXE and the DLLS are already resident on the user PC and all that is downloaded to the user is a rather tidy and small WBC file.
