[gdal-dev] AVCBin driver really slow on e00 data

[Ari Jolma]

I have a fairly large (43MB) e00 ascii data file. ogrinfo spends a 
couple of minutes to report that it contains ARC, CNT, LAB, PAL and RPL 
layers. The command

ogrinfo x.e00 PAL

opens the file and reports eventually that there are a certain number of 
features and then seems to take forever. PAL is a polygon feature class. 
ogrinfo on LAB points works much faster.

Why is it so time consuming to look into polygon features inside e00?

Regards,

Ari
