[Gdal-dev] linux vs windows performance

[Ed McNierney]

Matt -

I guess you've proven the benefit of translating from network to local
disk!  There is no particular reason (given the limited info you gave)
to think that the OS makes much if any difference.

Was the Windows copy from one local disk to the same physical local
disk?  And was that an IDE disk?

Hello,

In case anyone wonders about the relative performance of gdal on Windows
vs Linux:

Test case: gdal_merge of 154 dems in ArcInfo GRID format totalling 1gb.

Windows, from local disk to local disk:	1hr 15min
Linux, from network to local disk: 15 min

linux machine is 450Mhz & 768mb ram,
Windows is 3Ghz & 2Gb ram,
both dual xeons

cheers,
