Problem Note 40528: Slow performance of DBCS SAS® when UPCASE() function is used
 |  |  |  |  |
Performance problems with DBCS (Asian language) SAS will be seen in the UNIX environment if the UPCASE() function is used.
The UPCASE() function has been internationalized, and can be used with strings containing DBCS characters. However, if a string has many character-set boundaries, performance degrades.
