I haven't used Thunderbird in a long time, but regularly used Outlook with multi-gigabye .pst files. Surely sqlite on an SSD would be up to the task of handling at least million emails of average size.
What has been your experience? Mine in trying to use and support it is that Outlook is an Exchange client; PSTs are hacks to meet demand, though they work well enough in limited circumstances. Especially PSTs over a LAN connection are a disaster.
OT but is that right? SSDs have many advantages but sequential read isn't necessarily one of them. SSDs seek is much faster, but this is ~one file. Throughput can be much faster due to the better interfaces, but is throughput the bottleneck for this kind of search?
Yes, I know it's also an GNUStep application
