Compiling - no sse2 and high mem usage

UR-Quan

Greetings.

An hour ago git-clonned and compiled feathercoind with gcc7 by autogen.sh, configure --with-gui=no, make and make install on Ubuntu 17.10. Having some issues.

It says “feathercoin SSE2 unsupported, optimisations disabled” though my cpu clearly supports them:

“model name: AMD Phenom™ II X4 965 Processor”
“flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nopl nonstop_tsc cpuid extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt hw_pstate vmmcall npt lbrv svm_lock nrip_save”.

“export CFLAGS=”-march=native"" did not help.

feathercoind eats up 800 mb of RAM. “maxmempool=15” in .conf reduced the footprint by ~40 mb.

Please advise.

Currently what you describe is the standard behavior of feathercoind.

We need to work on the SSE2 detection at daemon startup.
The memory consumption is known.
