testnet3 node sync process is very slow My config file is similar to this:

testnet=1
blocksonly=1
rpcport=5000
server=1
listen=0
prune=1000  
dbcache=16000 
rpcallowip=0.0.0.0/0
rpcuser=someuser
rpcpassword=somepass


I have started the node sync in testnet mode and I tried to check the status by using the command 

$ tail -f testnet3/debug.log

...and keep on getting the same 

Again I tried this command to see the peers info 

$ bitcoin-cli getpeerinfo
output:
[
]


It means there are no peers, so I want to know what is wrong. 

The syncing is happening from more than 13 hours, but still headers and blocks are 0 only.

$ bitcoin-cli getblockchaininfo
{
  "chain": "test",
  "blocks": 0,
  "headers": 0,
  "bestblockhash": "000000000xxxxxxxxxx",
  "difficulty": 1,
  "mediantime": 1296688602,
  "verificationprogress": 5.667000646249453e-08,
  "initialblockdownload": true,
  "chainwork": "0000000000000000000000000000000000000000000000000000000100010001",
.......
are you running bitcoin testnet3?

put these lines to your conf file, shutdown and restart syncing again
