TMapFile.Update() too slow?

Hi Rooters,

I found that if I have a loop where I fill, say 20-30 histograms
("on-line") I can get about 250kb/sec filling speed (or rather a data
flow which goes from EventBuilder to Producer) on a "fast" computer.
Then if I add TMapFile.Update(); at the end of the loop, the data flow
goes down to 5-10kb/sec. Is it something what should be expected?

PS. Actually I don't need to update the file every time I go through the
fill loop but anyway ...

Best regards,
