I wonder if there is something wrong with the servers, my primesperspec went down from this,
16:57:09

{
"blocks" : 78031,
"currentblocksize" : 1159,
"currentblocktx" : 1,
"errors" : "",
"generate" : true,
"genproclimit" : -1,
"primespersec" : 3643,
"pooledtx" : 1,
"testnet" : false
}
to this,
21:31:48

{
"blocks" : 78416,
"currentblocksize" : 201426,
"currentblocktx" : 11,
"errors" : "",
"generate" : true,
"genproclimit" : -1,
"primespersec" : 109,
"pooledtx" : 14,
"testnet" : false
}
Even my processor is working all 6 cores at less than 50%.
Is this normal?
