Hi all, I have a VPS 4GB quad-core with 400G disk. For the last few months the electrum server is waaay slow, asking >1000s to process a block sometimes. Now hundreds of blocks behind. CPU is low, disk only about 5MB/s, memory is not over in use (zero swap in use). What can I do to make it faster? I can't understand what the problem is. Thanks for any help.
(I posted to /r/electrum but got no answers)
