Re: Replace is painfully slow and loses data
When performing a wide search/replace operation such as :%s/\t/ /g to replace tabs with four spaces in a 2000-line file, I get three problems:
* the operation is incredibly slow: 43 seconds on my machine (a quad-core with 8 GB of RAM) whereas the same operation in vim takes a split second
* undoing is almost equally slow: 32 seconds
* undoing often stops at random locations, with no obvious way to complete the undo sequence (further pressing the U key does nothing).
This is Microsoft Visual Studio 2008 Version 9.0.30729.1 SP on Vista64, with ViEmu evaluation copy 2.2.9. All third-party plugins such as VAX were disabled for this test.
