For unknown reasons, at some point, this function has become very slow.  Specifically, if you are doing a globalreplace on a large file--such as adding linefeeds to an EDI file for example--then the results are extremely slow.  For example, a 1 megabyte text file will take 5 minutes to process with this function.  A 60 meg file with take 5 hours.

By way of comparison, you can do this same sort of thing in .Net in seconds.  You can load the file in notepad++ and do a search/replace in just a couple of seconds.  Those are acceptable time frames to accomplish this task by todays standard.

We've worked around this issue by fabricating our own version of the of_globalreplace function that uses a database function in sql anywhere.  But we are still baffled as to why this function has become so incredibly slow.

 

Thanks,

Derek
