The average data collection results in 2TB+ of data. At 1Gbps transfer speeds (ie: a common internal wired networking) it would take 6+ hours to transfer that amount of data locally from start to finish. The further your location is from our site, the slower data transfer rates are likely to be. The emsl#msc Globus endpoint available to PNCC users has been observed sending data via Globus to Arizona as fast as 275 megabytes/second. At that rate, one terabyte can be transferred in about an hour. In comparison, a poor cross-country connection has been seen to perform as badly as 250 kilobytes/second, in which case that same terabyte would take a month and a half to transfer demonstrating the need to tune network connections at the user institution.
