  Hi,

  We are using GcExcel V6.0.2 and when upgrade to latest version V6.2.1 we noticed a dramastic performance degradation for our use case. Please see attachment for reproduction. The V602 project is using GcExcel V6.0.2 and V621 project is using V6.2.1. The code and input file is the same but as a test run the result is 2.1 seconds with V6.0.2 and 10.7 seconds with V6.2.1.

  It is very critical for the performance in our product and this performance degradation is preventing us from upgrading the library and we are hoping we can get the same performance as the old version. Please help to take a look at this issue. Thank you.

  Regards
