Very slow first start on Raspberry PI Zero #16

Closed dusan-ivanco closed 4 years ago

dusan-ivanco commented 4 years ago

This unofficial amrv6l version (12 and 13) is very slow on rPI0

First start after boot node -e "console.log('Node.js loaded');" takes over 2 min Official build (11) is ok

rvagg commented 4 years ago

@bnoordhuis any chance you can provide hints for debugging this?

I don't have a zero running at the moment, but on a Pi 1 B+, which isn't too different from a zero:

$ time ./node-v13.11.0-linux-armv6l/bin/node -e "console.log('Node.js loaded');"
Node.js loaded

real    0m1.874s
user    0m1.695s
sys 0m0.139s

So I can't replicate the problem myself.

dusan-ivanco commented 4 years ago

Which hints do you need for debbuging?

I have buildroot and my time is

real 2m9.900s user 0m1.199s sys 0m0.153s

now i see, that official build 10 have same problem as your 12 and 13 for me only official build 11 is working as expected

@dusan-ivanco Can you post the output of strace -T -tt node -e "console.log('Node.js loaded');"? If it's too unwieldy, insert -o trace.log before -T to capture it to file.

It could be that it's stuck trying to read from e.g. /dev/urandom; strace will show that.

dusan-ivanco commented 4 years ago

Yes, you are right

`16:44:29.145641 getpid() = 380 <0.000074>

16:44:29.158906 getrandom("\x20\xcf\x03\x1c\x96\x5e\x77\x9f\x41\xf3\xf5\xe6\x7e\xcd\x88\x96\x65\x4c\xf8\x96\x86\x77\x88\x2b\xb3\x2f\x1a\x85\xed\x8d\xf6\xf9", 32, 0) = 32 <189.181546>

16:47:38.341138 getpid() = 380 <0.000088> `

but why? why build 11 is ok?

bnoordhuis commented 4 years ago

It's an openssl bug that was fixed recently-ish - it didn't always wait until sufficient entropy is available. Node.js v11.x is out of support so it didn't (and won't) get the fix.

I'm going to close the issue because it's ultimately a problem with your system, not node. Google around for "getrandom slow" to find out more.
