Datapump takes a long time to import stats on remap schema import

112887Jul 6 2006 — edited Feb 5 2009

When importing a schema using datapump, everything imports at the expected speed but for some reason when it gets to

Processing object type SCHEMA_EXPORT/TABLE/STATISTICS/TABLE_STATISTICS

This takes about 30 minutes on remapped schema but for non remapped it takes less than 5 minutes

For a schema I am importing from a dumpfile of less than 40Mb the data and all objects takes less than 5 minutes to import

My export and import statements are

expdp system/admin123@intl DUMPFILE=exports:expdpshrink.dmp LOGFILE=exports:expdpshrink.log SCHEMAS=shrink JOB_NAME=expdpshrink

impdp system/admin123@sales DUMPFILE=exports:expdpshrink.dmp LOGFILE=exports:impdpexpress.log REMAP_SCHEMA=shrink:express JOB_NAME=impdpexpress

Is this expected behaviour? With no option to not process statistics on export/import in datapump, this is quite a problem for me as I regularly do remap.

Thanks
Chris
