I've used LD_PRELOAD few times to manually add timestamps to 10051 OPI event
traces (as oracle doesnt write timestamps for that trace)
 
Also, here's a clever trick for speeding up applications using time() call
excessively ( this is not oracle related ):

Hi,
I have only ever had to use this to replace a system library, with one
needed to implement specialized memory allocation, I never heard of it being
used in reference to performance.

Hey all, has anyone ever used LD_PRELOAD to resolve performance issues?
Our Unix guy says that they have used this setting in the past with
great results.   I've searched metalink and the documentation but 
haven't seen anything for performance. The main reason for its use, that
I can see, is to resolve some shared library errors.

Thanks
