Gmail and IMAP: less than

For some mysterious reason, imap.gmail.com gives the results of the query in groups of 100 pieces, making pauses between groups of a few seconds. Squeeze imap-clients or what? Getting a folder header of 10,000 emails takes about five minutes.

It has long been observed wild brakes work imap-clients with gmyl, but only now got around to see what's going on at the lowest level. And brakes are happening there. Information is given in packs of one hundred entries exactly.

I resent.
