NCEP and EC grib download speeds.

[MClarkson]

Anyone else notice NCEP(nomads) and Environment canada downloads going horribly slow over the past few weeks, especially during peak GFS and GEM download times? Ive got 2 servers... one seems to be going a little faster than the other but both are struggling... some 30-120KB/s depending on the server.

NOMADS always seems to burp now and then, you might do better using one of the raw data sources at NCEP?

I switched one of my servers over to the NCEP FTP last night, and the result was even worse. I feel like the performance goes back and forth, Ive been using nomads for the last year and a half or so, and before that the FTP was faster. But now everything seems to be crawling, at least during peak times. Off-peak is better, i'm seeing 300-900KB/s or so, at least for the GEM test I just did(4 hours after the 12Z run was available).
