I've upgraded noisetor to 17-rc. We were seeing memory consumption exceeding 2GB/daemon (leading to swap storms on our 4-daemon 8GB box), I'll keep an eye on it to see if we do better with 0.2.4. After 20 minutes of uptime with 17-rc I'm not seeing the CPU pegged like it was within minutes of restart with 0.2.3.25, even though we are pushing 220 Mbps already. According to "perf top" we're still spending a lot of time in circuit creation/teardown though: cycle% image symbol ------ ----- ------ 19.37% tor circuit_unlink_all_from_channel 11.56% libcrypto.so.1.0.0 bn_sqr4x_mont 5.74% tor circuit_get_by_rend_token_and_purpose.constprop.11 4.95% libcrypto.so.1.0.0 sha1_block_data_order_ssse3 3.56% libcrypto.so.1.0.0 bn_mul4x_mont_gather5 3.20% libcrypto.so.1.0.0 _vpaes_encrypt_core 2.03% libcrypto.so.1.0.0 _bsaes_encrypt8_bitslice 1.32% libssl.so.1.0.0 ssl3_cbc_digest_record -andy _______________________________________________ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays
