increase number of files requested in document list

[jcline]

With a few thousand files, it's currently pretty slow even on a fast connection... The default is 100 files/request. Would changing that to 1000 slow down requests for users with <= 100 files? Would it be faster than 10 requests? Would a dynamic increase be more sensible? That is, request 100, then 200, then 400, then 800, etc. The limit is stated as 1000.

One thing worth checking on is if, now that the connection during the file list phase isn't destroyed and libcurl may be able to reuse it, this reduces the time required enough to reduce this value from 1000.

I should ask the Google Drive folks during their next office hours what they think is a good approach for the different use cases.
