Is there a way to speed up initial sync process?
It is lasting for the 3rd week and seems to ever slowing down as I am close to 90% of blocks.
I am running full node on my server.
Funny thing is that even full bitcoin core sync on the same server took just 10 days while ethereum seems to stuck.
There is no eth bootstrap, am I right?
I have turned everything off, leaving geth to utilize whole server and bandwidth. It does sync occasionally, but most of the time it is looking for peers.
I have tried various geth options – no luck.
geth.exe --fast --cache 512 --maxpeers 100 --maxpendpeers 25 --v5disc --verbosity 5 console shows mostly these errors while looking for peers:

Update: there were time sync errors; After syncing time on server I am getting other errors:

There is no way to speedup initial sync. Make sure network ports are open. Make sure node have correct time. Then just wait.
Update: Make sure you have correct time:
Run time.is or similar online time checker. If there is more than a 10 sec difference you have time sync problem.
Normally you use NTP client to keep your machine synced with correct time. Each modern OS does it automatically for you.
For windows it may be enough to just turn internet time sync on and use
pool.ntp.orgas a source.If you want more control - check this link.
If you a pro, I would recommend using Meinberg NTP service(server included) instead of standard windows'
w32time.For Mac and *nix - just check NTPd. See example here.
