Updated my comment:<p>&gt; easily capable of hashing and encrypting the data much faster than SpiderOak was handling it<p>I can believe that there was upstream congestion somewhere outside my network (speeds to Google, Amazon indicated that there were no issues inside) or that their server was overloaded but the engineer who investigated seemed to attribute it to the client:<p>&gt; Additional changes to storage network configuration will not improve the situation much. There is an overhead limitation when the client encrypts, deduplicates, and compresses the files you are uploading&quot;
