This is quite an old question, but nobody mentioned the fasted way (but also the most challenging) of updating/creating huge amounts of records in CRM 201X - using built-in import feature, which is totally doable using CRM SDK. There is a perfect MSDN article about that:
https://msdn.microsoft.com/en-us/library/gg328321(v=crm.5).aspx. In short you have to:
1) Build Excel file containing the data you want to import (simply export some data from CRM 201X and check how the structure looks like, remember that the first 3 columns are hidden)
2) create Import Map entity (specify the file you created)
3) Create column mappings if necessary
4) Create Import and ImportFile entity, providing proper mappings
5) Parse data using ParseImportRequest
6) Tranform data using TransformImportRequest
7) Import data using ImportRecordsImportRequest
This were the steps for CRM 2011, now in 2017 we have more versions available and there are slight differences between them. Check the sample that is available on MSDN and in SDK:
https://msdn.microsoft.com/en-us/library/hh547396(v=crm.5).aspx
Of course point 1, will be the most difficult part, because you have to build XML or docx file perfectly corresponding to what CRM expects, but I'm assuming you are doing it from external app, so you can use some great .NET libraries that will make things much simpler.
I never saw anything faster than standard CRM import when it comes to updating/creating records, even if you go for parallelism and Batch Update requests.
If something goes wrong with the MSDN sites, I'm posting here an example from the link above that is showing how to import data to CRM programatically:
