[svn-r19757] Purpose:
Improve h5diff performance.
Description:
The following changes for improving h5diff performance:
1) use HDmemcmp() before comparing each elements
(memcmp() is very fast at both linew and jam)
2) replace the expensive H5Tequals() calls
3) retrieve datatype information at dataset level not each element level
for compound datasets
Tested:
jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE)
