64-bit Hash Files
Posted: Fri Mar 13, 2015 10:21 am
Hi All,
We migrated from v7.5 on a 32 bit Windows Server to v9.1 on a 64 bit Windows server. We use Server Jobs Only
Post Migration we are having performance degradation in the newer version by almost 40% while I understand a 10% down performance can be expected due to the way Authentication works.
** No Code Changes made during upgrade **
We have done a lot of testing but have not been able to figure out why the same job in 9.1 is so slow compared to 7.5. Have raised a support request with IBM but that is not helping!!!!!
We use a lot of Hashed Files and currently both version have the variable 64BIT_FILES = 0 in the UVCONFIG file. Any chance changing this 64BIT_FILES = 1 in the v9.1 to use 64 bit Hash files instead of 32-bit could help in performance?
Thanks,
NV
