Drop in download speed

[lbusett]

From HG issue reported here, #64

With the hotfix version download speed was reduced dramatically and I got the error
Warning #messages:
1: running command '"aria2c"' had status 1

I have just downloaded the "devel" version and I am still getting the same warning message
1: running command '"aria2c"' had status 1

I opened a new issue. This is strange. We'll check it next week.

Hi Helene,
can you tell me if you're using ftp or http download ?

Hi Lorenzo - I am using http.

On linux, I'm not seeing changes in speed nor warnings - will check on windows ASAP.

Hi Helene,
I made some tests on this product both on Linux and Windows, without being able to reproduce this issue: download speed resulted high (normal) both with aria2c and wget. Could this issue be related to NASA server's problems, or to problems with the connection to it? Maybe check it again during next days.

Ps. recently we updated the ProdOpts file in order to shorten product names: after this update, already processed products are re-processed, since names changed. This would not have consequences on download speed, since hdf file names did not change, but could increase total processing time.

Thanks Lorenzo for looking into this issue. For one year of data (NDVI, VI quality, composite day of the year, pixel reliability, land/water flag) it is taking me approx. 16 hours and with the error message "running command '"aria2c"' had status 1"
I will try download the data on a different day later this week.

Hi Helene,

I committed a new version in devel: efbf1b4

It should solve the warning running command '"aria2c"' had status 1, and also some other problems on download (hopefully, it should also improve speed in some cases) . Try it out if you wish.

By the way: download speed from NASA server is greatly variable. As a rule of thumb, however, the highest speed should be obtained with ftp download, with aria2c option activated.
