I'll reply here… I've just tested the latest snapshot (aka the 0.4 release) via VPN. The basic test is starting a mintty from a cmd prompt and have mintty run some program depending on the test. I run two tests, one is just an "echo test" which uses the builtin echo of the shell that mintty just fired up, the other does a "git status". Connected via LAN the echo tests take all under a second now save for a few excursion when I didn't start cygwrunserv that were around 1.5s. The git test takes a bit longer depending on whether I start it on a network share or a local directory, but completes in under 2s. Now, connecting via the VPN and not running cygserv I get 2s for the echo test and 47/42/6 seconds for git status on two different network shares and a local repository (these repositories are all fairly small, just some local configuration stuff). With cygserv running, these times change to 1/49/5/5 seconds (yes, it took two seconds longer on one of the network shares). As it happens, I can force the VPN to connect almost exactly from the other side of the globe, which will produce a long roundtrip time (unless you are having a satellite link in there somewhere or really stupid routing it can't get much worse than that). In this case, with cygserv running I get 15/840/40/85 seconds. Without cygserv, this becomes 39/789/-/95 (I skipped one of the network shares for this test). Again there's one network share that had better performance for the git test without cygserv. Another interesting bit is that the echo test time actually depended on whether the working directory was on a network share (resulting in 39 seconds) or on the local drive (where it only took 26 seconds). So, those changes in the latest snapshot look good from that perspective and the remaining delays, at least with cygserv running are in any case not attributable to the LDAP integration. I don't have an old Cygwin installation o that machine anymore, but the results w/ cygserv on the long latency link match my experience of using that long latency link "for real" about a year ago.
