mac extremely slow (randomly), memory full, CPU fine

Am struggling to troubleshoot what is wrong but Mac performing super slow (occasionally will free up for a min or two). Upgrade to El Capitan - didn't help or hurt. reset PRAM and SMC. Freed up space on HD (23% free). Disk Utility/Onyx run and no issues (except for permissions). Watch Activity Monitor and don't think it is CPU. memory is now full but wasn't always - Kernal_task highest usage (450MB). Disk usage spikes occasionally (but not sure connected to issue). Indexing off. Created a new account to logon; same problem. Any suggestions to troubleshoot would be greatly appreciated.
