New member Jim is looking to improve his speed index and asks which part(s) of his server's hardware he needs to upgrade to improve it. He's running a Xeon E3-1230v3 with 16Gb RAM, a couple of SSDs in RAID1, and CentOS 7 with DirectAdmin for his control panel. Suggestions are already coming in to upgrade the CPU and/or switch the storage to NVMe (or just change the SSDs for a better model), but is he going the right way about this? Hardware is hardly ever the complete answer, so what other steps should Jim be taking to narrow down any bottlenecks which might help improve his speed index without having to swap out hardware or even move to a new server? Share your thoughts in the thread.
Microvax first started this thread almost exactly a year ago, but it keeps on coming back to life and seems to be one of those recurring issues that just refuses to go away. He'd noticed that a RBL seemed to be blocking his server's IP so did some Googling and discovered that it related to OpenSRS, but couldn't find a direct way to contact them regarding this problem. 10 months later he finally managed to contact OpenSRS via email and after 5 days they responded removing his IP from their blocklist. But that's not the end of the story because less than a month later they blocked his IP again. 2 weeks later he was blacklisted again. He got in touch again and they responded "In order to whitelist the IP permanently, we would need the sender score to be higher. Currently it is showing as 79." Has anyone else had issues with this blacklist or others repeatedly blocking IPs. RBLs exist for good reason, but should there be easier ways (maybe a standard system?) to contact them and resolve issues like this?
